Some Frequently Asked Questions that came up about Air Purifiers…

Q: What causes indoor air pollution?
A: Modern constructed houses are sealed firmly for energy efficiency. Energy efficient homes are excellent to reduce your electric costs, but terrible for your allergies. Normally all types of contaminants in home are pollen that blows in when a door or window is opened, cat dander that hitches a ride on clothing, chemicals and irritants released by cleaners or cooking and volatile organic compounds from furniture and carpet. Pollutants like cigarette smoke, pollen, mold, dust, and animal dander can cause asthmatic and allergic reactions, making homes unpleasant and unhealthy for allergy and asthma patients. The contaminants, like chemically reactive gases, can cause allergic reactions with some being carcinogenic and toxic.

HEPA filter media is composed of millions on very thin fiber-glass fibers that combine to form a fabric like paper. As air passes through it, allergens such as pollen, animal dander, mold spores, and dust get trapped in the tiny filaments of the filter. Many HEPA air purifiers also contain a carbon filter to capture chemicals, odours, and gases. Once the dirty air has pass through all the filtration stages, then it sends clean air back into the room.

A: For optimum operation, it is recommended that you should run air purifier continuously. If noise is a concern for you, run it at higher speeds as you are away for work or school then turning the fan speed low to quieter levels before bedtime or when you come back home.
Q: How often there is need to replace the filters?
A: Typically, you need to replace the carbon filters after every 3 months, and main filter annually. To cut costs, look for room models that are Energy Star certified, meaning they are relatively energy-efficient compared to standard models. Some models have washable filters that can be reused. In general, low-priced air purifiers require replacement once a year, with more expensive brands recommended three to five year replacement intervals.
Q: How noisy are air purifiers?
A: Before you buy your air purifier, if possible, ask for a demonstration of the unit how it works and see the noise level.  Some air purifiers are tremendously quiet, while nearly all can be pretty noisy when operating at high power, and many of air purifiers, there are decibel ratings mentioned on it.

  1. I suffer from spring allergies but I did not realize how much our indoor air could effect the medical condition. Your statistics were overwhelming.
    This review is very helpful and full of information that helps make the buying of a indoor air purifier much easier.
    You even have pictures and prices to go along with the descriptions. That is very helpful for someone like me who is more of a visual person also, my own air purfier has not given me the results I need and I will more than likely take on both the Holmes and Honeywell to get extra benefits

  2. Thanks for the review about Air purifiers as we have on-going issues here at home. It has became a lot  more clearer to me about how and what air purifiers to use at home or at a small office. Thanks also for outlining your tips and useful steps as I have certainly learned something new today. From this list, my preferences are for the GermGuardian followed then by the Honeywell True hepa air purifier and the price at Walmart is usually one of the lowest you can get anywhere. Learned a lot from your FAQ list so cheers once again for that

  3. Thanks Paul for this awesome piece of information on Air Purifiers. The last air purifier I got gave was simply an awful experience, I had to return it after a month as it caused problem after problem. The list you have on this blog has awesome features. “The winix plasma wave room true hepa air purifier” looks like the best option for me anyway – hopefully it will work a lot better than my last one!

  4. Has anyone been able to find out which is the best product among those listed here? Good tips and faq’s though, Honeywell is a brand that I have used before and they never let me down before so I guess I would select their brand as I know them better than anyone else
