Can I use the air purifier that I purchased from you overseas?

The air purifiers we sell are safety tested and approved for 120V outlets only. They will be damaged if plugged into a 220-240V outlet, and the use of a transformer or adapter may not eliminate the risk of damage. Manufacturers will offer no warranty coverage or refunds on air purifiers that are used outside of North America. If you are interested in an air purifier for overseas use, Austin Air and AllerAir offer custom-built units for this purpose. Contact us for pricing and delivery times.

General Questions About Room Air Purifiers

How large are the units?

We sell room air purifiers small enough to put on a night-table or desk, and portable enough to take with you to the cottage or on vacation to clean the air inside your hotel room. However, the typical room units we sell are about the size of a dehumidifier.

Air purifiers designed for specialized business and industrial use can be larger, depending on the model.

How much do they cost?

The high-quality air purifiers we sell here at Modern Alchemy Air Purifiers start from as little as $300.

I see air purifiers at my local hardware store selling for $100-$200. What’s the difference between them and the ones you sell?

In general, the cheaper units do not move large quantities of air through them because their motors are not powerful enough or because their inferior design allows air to bypass the filter. This results in drastically reduced air cleaning efficiency. In addition, depending on the amount of pollutants in the air, the small amount of carbon found in many substandard air purifiers can be depleted within weeks, making the unit useless.

Other major issues with low-cost units are reduced reliability, higher operating costs, difficulties in finding replacement filters, and in some cases, toxic off-gassing or ozone production.

More about substandard products and the Modern Alchemy Difference

Do you sell any used air purifiers at reduced prices?

We occasionally sell our demo models or open-box units at reduced prices. These units come with a full warranty. Please visit Promotions & Specials or contact us to inquire about availability.

Are air purifiers only available in boring colours like white and black?

Absolutely not!   Even through some people prefer to have their air purifier in a neutral colour, many models we offer are available in a number of different colours to match practically any décor, from elegant sandstone or midnight blue, to bolder colours from AllerAir like red, green, copper and yellow. We even offer blue and pink units from Austin Air for the baby’s room!

How will I know if my air purifier is actually removing harmful contaminants from the air?

Although air purification is generally an invisible operation, through the use of a particle counter or professional air quality assessment, we can see that the number of particles or level of toxins in room air is dramatically reduced after using a high-quality air purifier to clean the air.

In addition, looking at a pre-filter or HEPA filter after long-term use can provide you with visual evidence that contaminants have been captured (especially if you have a pet or a smoker in the house!).

If I purchase an air purifier from you, does that mean I don’t have to dust or vacuum anymore?

NO!   By running a room air purifier constantly, you can significantly reduce the amount of airborne dust in a room, but you still have to vacuum and dust on a regular basis to pick up the heavy particles that have settled on the floor and furniture.

General Questions About Whole-House Air Purifiers

Can a whole-house system be installed in any home?

In general, a whole-house air purification system can be installed in any home with a furnace. On rare occasions, however, space limitations or ductwork configuration can restrict the type of system that can be installed.

What is the difference between a bypass whole-house system and an inline system?

A bypass system will take approximately 30% of the air being returned to the furnace by the HVAC system and clean it using both a medical-grade HEPA filter (for particles) and activated carbon (for chemicals, gases and odours). An inline system will clean 100% of the air that is drawn into the HVAC system, but removes only particles.

See our complete selection of Whole-House Air Purifiers

Do I need to run my heating or air conditioning constantly for a whole-house system to function?

No.   As long as the fan in your HVAC system is set to the “on” position instead of “auto,” the whole-house system will continuously deliver purified air to every room of your house.

What are the advantages of a whole-house system over individual room air purifiers?

Whole-house systems are appropriate for people who do not have medical conditions and are just looking for basic air cleaning in their home. They are perfect for houses with many small rooms, large open spaces or cathedral ceilings. They are also good for people who lack the space for portable air purifiers, are sensitive to the noise generated by some room units or prefer their air cleaning system to be out of sight.

What are the disadvantages of a whole-house system compared with individual room air purifiers?

While excellent for general purpose air cleaning, people with allergies, asthma, chemical sensitivities or other respiratory issues should consider individual units. Portable air purifiers are much more effective for people with medical conditions because they can perform up to 8 complete air exchanges per hour within a room, compared to just ½ or 1 air exchange per hour for even the best whole-house system.

Can I use a whole-house system in conjunction with individual room air purifiers?

Definitely!   In fact, we recommend that customers address specific air quality concerns first with individual room air purifiers (e.g., in the bedroom or at the source of the pollutants), and then install a whole-house system for added protection and maintenance through the entire house.

How much does installation cost?

It depends on which system you purchase. The Blueair Central Whole-House Filter System requires no professional installation; simply replace your existing furnace filter with the Blueair Central filter and plug the MX2 particle charger into any electrical outlet.

Installation is included in the price of the IQAir Perfect 16.

For other systems, a professional HVAC company will normally charge $150 - $250, depending on ductwork accessibility, materials needed and overall labour.

Do you do the installation for the units that you sell?

Except for the IQAir Perfect 16, we do not provide installation services. However, if you are located in the Ottawa/Gatineau region, we can recommend several professional contractors/HVAC companies who have experience installing the systems that we sell.

Operation and Maintenance of Air Purifiers

Can I leave my air purifier on all the time?

Yes!   The air purifiers we sell are designed and built for continuous use. In fact, we encourage customers to leave their air cleaner on at all times to achieve the healthiest living environment possible.

What impact will running an air purifier have on my electricity bill?

Although it will depend on the model chosen and the setting that you run it at, a typical air purifier should cost less than a penny (0.7 cents) per hour to operate, or about 17 cents a day if you run it constantly.

Are air purifiers noisy?

Because powerful motors are used to draw air into the unit and force it through the HEPA filter, high-quality portable room air purifiers can be fairly noisy on their ‘High’ setting. The first time that you turn the unit on, it might seem rather loud to you. However, because the unit creates “white noise,” much like the noise made by your furnace, air conditioner or refrigerator, most people stop noticing the sound within a couple of days.

Also, some people run their bedroom units on the highest fan speed during the day and turn it down to a lower setting when they are sleeping.

If noise issues are a major concern, we recommend purchasing a Blueair air purifier. With their innovative HEPASilent™ technology, Blueair units are able to effectively clean large volumes of air at much lower decibel levels. Other ideal choices if noise is an issue would be the powerful, yet ultra-quiet Epurair MA-1P, and the #l rated air purifier in the world, the IQAir HealthPro Plus (New Edition).

Are the air purifiers you sell complicated to use?

Definitely not!   For most of the air purifiers we sell, you simply plug the unit into an electrical outlet, turn it on, and set the fan speed you desire. Nothing could be easier!

Should I purchase a unit whose specifications match my exact room dimensions?

Actually, we recommend buying a unit designed to clean the air in a larger room. This way, you can operate the air purifier at a lower fan speed setting and have it run more quietly.

Where should I place my air purifier in the room?

To achieve maximum effectiveness and performance, the unit should be placed at least 8 inches from the wall (12 inches for IQAir models).

What maintenance is required to keep my air purifier performing at peak efficiency?

The maintenance schedule varies depending on the unit selected and the concentration of contaminants in the air. For Austin, AllerAir, Epurair and IQAir air purifiers:

  • Pre-Filters – can either be vacuumed occasionally or changed every 3 to 4 four months. IQAir pre-filters should be replaced every 6 to 18 months.
  • HEPA Filters – should generally be changed every 2 to 5 years.
  • Activated Carbon – is usually replaced every 2 to 5 years (or 1 to 3 years for IQAir and Epurair models).
  • UV Lamps – if applicable, should be changed every year.

All Blueair air purifiers require replacement of applicable filters once every 6 months (and purchased from an authorized Blueair dealer) for the warranty to be valid.

Is it difficult to change the filters?

Not at all!   The filters can be changed in a matter of minutes. Most units simply open (some models require the removal of 4 screws) to allow you to pull out the old filter and insert the new one in its place.

How expensive are the components that need to be changed?

Here’s where our expertise can help you select an air purifier that will not only offer outstanding performance, but also be more cost effective to operate in the long-term. Replacement filters in low-priced models sold in department and hardware stores can cost almost as much as the unit itself and need to be changed much more frequently than the filters used in the high-quality units that we sell. Here’s one example:

A typical budget unit might sell for anywhere from $100-$200. Not even taking their poor performance into account, the filters can cost over $150 to replace and need to be changed every year.

For the AllerAir AirMedic Pro 5 Plus, one of Modern Alchemy Air Purifiers’ most popular models, the filter costs are normally $92 per year. This includes:

  • Pre-filter – $0, if vacuumed occasionally
  • HEPA filter every 5 years – $100 (or $20 per year)
  • Activated carbon canister every 3 years – $215 (or $72 per year)

Over a five-year period, that’s a savings of $290 over the department store model!

For even greater long-term savings, Austin Air purifiers offer the lowest maintenance of any air purifier on the market that requires filter changes. For example, the HealthMate HM-400 unit not only provides outstanding air cleaning performance, but the $285 combination HEPA/activated carbon filter only has to be replaced every five years, resulting in an up-keep cost of just $57 per year!

With my busy schedule, how am I supposed to remember when to change the filters in my air purifier?

By joining Modern Alchemy's Filter Replacement Program (FRP), you can relax knowing that we will send you an email when it’s time to change a component in your AllerAir or Austin Air unit. If you are the proud owner of an IQAir or Blueair air purifier, the machine itself will tell you when it’s time to replace a filter! Best of all, as a member of our free program, you will receive exclusive savings on all replacement filters.

Air Purifier Applications

Will an air purifier make my allergies or asthma go away?

Unfortunately there are no cures for asthma and allergies, but many people have found that these conditions can be improved by the use of high-quality room air purifiers throughout the house, as one part of a complete allergy or asthma management program.

Can an air purifier help to improve the air quality in my baby’s room?

Yes!   We recommend the Austin Air Baby's Breath, a small and quiet unit that not only eliminates harmful contaminants from the air your baby is breathing, but even comes in pink or blue!

How can I protect myself from bacteria, viruses and mould spores?

A safe germicidal UVC lamp can be added to virtually all AllerAir air purifiers to help eliminate airborne bacteria, viruses and mould spores.

You might also consider an IQAir HealthPro Series air purifier. With IQAir's patented HyperHEPA™ filtration system, even the smallest airborne bacteria and viruses are captured by the HEPA filter.

An economical alternative is to use a maintenance-free Airfree air sterilizer in conjunction with a high-quality HEPA/carbon air purifier. These air sterilizers use heat to incinerate microbial pollutants, working together with the air purifier to provide full-spectrum air cleaning.

I love my pet, but my partner is allergic. Would an air purifier help us?

An air purifier alone can never completely remove dog dander, bird feather dust, cat allergens or general pet odours, but operating a specialized unit like the Austin Air Pet Machine can significantly reduce the allergen triggers in the air, making it possible for pet lovers and allergy sufferers to cohabitate.

Will an air purifier help to eliminate the mould growing on my basement walls?

An air purifier equipped with a UV lamp (available as an option on almost all AllerAir units), or an air purifier supplemented by an Airfree air sterilizer, can help to reduce the amount of mould spores, microbial volatile organic compounds (mVOCs) and mould mycotoxins (harmful toxins produced by some moulds) in your basement. However, it will not remove the mould that is currently on your walls.

Can an air purifier eliminate the smell and harmful effects of tobacco smoke?

Removing the source directly is always the best method to eliminate tobacco smoke, but if the smoker doesn’t want to smoke outside, there are specifically designed units that can help to reduce odours and adsorb some of the harmful chemicals found in second-hand tobacco smoke. Units like the AllerAir AirMedic Pro 5 HDS and IQAir MultiGas GC are specifically designed to deal with tobacco smoke issues.

An air purifier can also help in cases where smoke is entering your residence through the duct-work of an attached dwelling (e.g., town-homes, semi-detached houses, condos and apartments).

I have MCS. How can I ensure that the carbon in the air purifier will not affect my health before I purchase it?

We recommend purchasing an AllerAir Carbon Test Kit from us. This contains six different carbon blends that you can test to determine which is most suitable for you, helping to ensure that the activated carbon does not have any ill-effects on your health.

If you then decide to purchase one of our MCS specialty units (like our top-of-the-line AllerAir AirMedic+ MCS D), we will gladly reduce the selling price by the cost of the kit.

I find that food odours linger in my house for days. Will an air purifier help?

Proper ventilation is always the best way to remove cooking odours from your home, but operating a room air purifier with large amounts of activated carbon can help to control the odours you are experiencing.

Can I use an air purifier to get rid of dust and odours in my husband's basement workshop?

By operating one of our high-quality room air purifiers, airborne dust particles will be captured by the filters and odours will become trapped and neutralized by the activated carbon, thus helping to alleviate the problems you are experiencing. We can even recommend specialized units to handle specific chemical fumes or workbench models that help to remove harmful pollutants directly at the source.

People at the office drive me crazy with weird-smelling food and heavy perfume. Could an air purifier help?

By operating one of our small, quiet, personal desktop air purifiers like the AllerAir AirMed 1 MG, you can create and maintain a protected area or “bubble” around you, where contaminants and odours would have difficulty entering because you are continuously pushing clean air out into your work space.

Technical Questions

What is HEPA?

A HEPA (High Efficiency Particulate Air) filter is a tightly woven medium made from glass fibres that are pleated to maximize surface area for particle collection. HEPA filters are the most effective systems available for capturing fine particulate matter. True HEPA filters are capable of removing 99.97% of all particles as small as 0.3 microns (invisible to the naked eye) from the air we breathe.

Are all activated carbon filters the same?

No!   Activated carbon can be enhanced, impregnated and/or blended to more effectively handle the adsorption of specific chemicals and odours. For example, the AllerAir AirMedic Pro 5 Plus Vocarb air purifiers we sell have a larger and more refined blend of activated carbon and will do a much better job of removing harmful airborne Volatile Organic Compounds (VOC’s).

Does it matter how much activated carbon there is?

Yes!   Activated carbon adsorbs to its surface, so when it reaches saturation level, it is depleted of its capability to be effective and must be replaced. Large amounts of activated carbon will last far longer than smaller amounts because it has a greater area for adsorption.

Depending on the amount of pollutants in the air, the small amount of carbon found in many substandard air purifiers can be depleted within weeks, making the unit useless. We can supply you with an air purifier that contains one of the largest amounts of activated carbon available on the market today, which can last from 18 to 36 months.

What is a Volatile Organic Compound (VOC)?

Volatile Organic Compounds are molecular gases such as formaldehyde, dichloromethane and benzene that are extremely dangerous for your health. Modern Alchemy Air Purifiers offers selected units like the AllerAir AirMedic Pro 5 Plus Vocarb, the Austin Air HealthMate Plus and the IQAir GC Series designed with specially-blended carbon to specifically deal with VOC’s.

Do the air purifiers you sell produce harmful ozone?

No!   In fact, indoor ozone levels are actually reduced when operating our air purifiers because of the activated carbon contained in most of the units we sell.

What does MCS stand for?

MCS stands for Multiple Chemical Sensitivity. Multiple Chemical Sensitivity is a form of Environmental Illness (EI), caused by living in a toxic world. People with MCS feel uncomfortable or sick in the presence of specific odours. Chemicals such as pesticides, synthetic fragrances, cleaning products and detergents can all affect someone with MCS. We offer specialized air purifiers that can reduce many of the chemical fumes and odours from indoor air to help people living with MCS breathe easier.
