Air Purifier Reviews:

Air purifiers have been around for years, but it seems like recently the air quality reports and overall respiratory problems that people are experiencing have caused a buying spree for the ionic air purifiers. There is much controversy on how well they work. We know they help clean the air environment around us (that much is proven), but it's a matter of how much better the air quality is that really counts. For example the Oreck XL Professional Air Purifiers sell for $370 and at one point so did the Ionic Breeze Quadra from Sharper Image - so we need to determine if the price is justified based on the results of their performance. Consumer Reports reported not too long ago that the Ionic Breeze failed to clean the air significantly and actually exposed users to "potential high levels of ozone". I had owned 2 of the Sharper Image products due to our daughters indoor allergy problems and thought they were working good, but you just never know. Air cleaners, either for room or whole house purposes are a huge business. It's estimated that almost $350 million is spent each year on home air purifiers


Top manufacturers of air purifiers are Honeywell, Hunter, Holmes, Kemore, Austin, Friedrich, Blueair, IQAir, Oreck and Whirlpool. You can buy them at stores like Walmart, Home Depot, Lowes, Sears, and Target. They all have air purifier ratings and most claim to do their best work if you setup the air purifier to manage only 1 room roughly 20 X 30. You can even get a personal air purifier that travels with you if you are so inclined. The air purifier comparisons show that Oreck and Honeywell produce the best air purifiers. HEPA Air Purifiers - HEPA (High Efficiency Particulate Arrestor) is a type of air filter that is used in air cleaning equipment including things like vacuum cleaners. Most HEPA air cleaners will filter particles at an efficiency rating of 99.7%. They will filter and remove some of the smallest microns of allergens such as dust, smoke, pollen, animal dander. They work by filtering the allergens in the air through the HEPA filter which traps the particles, allowing only the clean air to circulate. Hence, the more times the air is forced to travel through the air filter, the cleaner the air will get. People with HEPA purifiers in their rooms find that they have less allergy and asthma symptoms while sleeping at night. Air purifiers, on the other hand, don't clean the air by filtration like HEPA air cleaners. The 2 types of air purifiers are ozone/ionizer. The ozone purifiers the air by oxidation (splitting the 02 molecule into 03 which is ozone). Ozone penetrates into odors, bacteria, and fungus molecules to create a clean smell. The ionization process is where negative ionic charges from the air purifier attach to airborne particles like dust, smoke, pollen, and animal dander forcing the particle to drop out of the breathing environment down to the ground. Prices range from $49 to $200 but keep in mind that the filter replacements add up over time (once a year they need to be replaced). Living with an air purifier is essential for those of us with asthma or other respiratory diseases that require the cleanest air quality we can get. Air purifier reviews - We found dozens of good independent reviews on websites like Amazon.com and Epinions. The few reviews posted on allergy product websites seemed more based on fear than anything else and results were mixed. Consumer Reports had the most thorough testing (26+ models) - they rated the air purifiers on ability to remove dust or smoke (at both high and low speeds), noise levels, ozone emissions, and annual cost to run the purifier for energy and filter prices. I have found that the noise levels are way to high on most purifiers. I bought the Honeywell Enviracare 50250 but on high speed it's hard to tune it out. Most purifiers scored well at low speeds for noise, but almost all did less than average at higher speeds. You can browse the top selling air purifiers online here.

Best Air Purifier:

From what we could find the Honeywell air purifiers dominate the listings on almost all websites that sell these. As we mentioned, noise can be an issue with some of these models but we feel like the Honeywell 50250 is a solid value at around $150. Yes, it does run a little loud, but so do the rest. Features 3 speeds with a filter-clean monitor and the HEPA filter removes up to 99% of particles such as germs and bacteria from the air. If a quiet air purifier is what you are looking for, then we suggest the Honeywell HFD-120-Q Tower HEPAQuiet Air Purifier with Permanent IFD Filter - Consumer Reports gave it the best score for noise levels on high speeds, but keep in mind that the overall efficiency of the unit at removing dust and smoke was not that great. We say stick with higher rated Honeywells and accept the louder operating noise.


Room Air Purifier:

When it comes to quality air cleaners that work best in larger rooms, it appears that the Rabbit Air BioGS is the leader. The Rabbit Air comes in 4 color choices - pearl white, metallic blue, lime green and chrome silver. It features an ultra quiet air purifier that requires little maintenance and owners appreciate that the filters are washable. There are zero ozone emissions and the 5 year warranty is something you don't see on most competitor models. This model is good for rooms up to 600 square feet - some reviews we read online were from people in small offices. The BioGS is energy efficient and many consumers call it the "best air cleaner on the market". The unit is quiet and performs quite well for those with allergy issues. At just over $300, the Rabbit Air is more expensive than most of the Honeywell air cleaners, but reviews from over 100 owners point towards this model if you have the money.

Top Rated Allergy Air Purifiers:

We scoured the top allergy sites online to see what they thought of air purifiers for allergies and found that their users consistently rate the Austin and IQ Air purifiers in the top 2. RECOMMENDED - The Austin Air Healthmate HM 400 Air Purifier took first place at a cost of $440 (with free shipping) with effectiveness up to 1500 sq/ft. They recommend using it in small apartments or large living room area in a house. The products rated well with allergy relief from mold, dust mites, and hay fever. You may have even seen the Austin HealthMate featured on the Today Show. The IQAir HealthPro Plus Air Purifier came away with the "Highest total system efficiency in the industry" and listed at $850. Perfect for allergy sufferers who need relief from odor or gas control. Our biggest complaint with the IQ Air is that it costs about $120 to run for an entire year and filters can cost another $200. That adds up over time.
