Air Purifier Comparison, Ratings, & Reviews

Since there are several important factors to consider as you compare air purifiers, we offer the following comparisons and ratings charts with reviews of different purification methods, technologies, and brands. Typical comparison aspects include effectiveness, initial cost, operating cost, replacement parts cost, noise level, maintenance, warranty, and money-back guarantee, with effectiveness being the most important. Most people want the best air cleaner to reduce pollutants and allergens, however very few products can effectively reduce a wide variety. There are many different types and sources of air pollution and allergens, and many, such as chemical gases, mold, and dust mites, are often hidden, invisible, or overlooked. The best purifiers effectively reduce or eliminate many different allergens, smoke, odors, germs, bacteria, viruses, mold, chemical gases, dust mites, etc. Performing your own review by trying air cleaners in your home or business is a great way to validate effectiveness and compare products.

Ozone Production Method Comparison

Biozone PureWave™ Photo Plasma

Corona Discharge (Older Method)

Constant ozone output,
predictable production

Erratic ozone production,
unpredictable production

SafeVolt
Low voltage (12 volts).

High voltage (5,000 - 10,000 volts)

SafeZone
Lower concentration per volume of air, safer ozone levels.

Higher concentration per volume of air, potentially harmful or unsafe ozone levels according to the FDA, EPA, and OSHA.

Pure ozone, free of byproducts

Produces irritating, dangerous byproducts (nitrous oxides, nitric acid, etc.)

No electrical noise

Generates electromagnetic radiation

Replaceable lamps

Replaceable corona element

Low maintenance, simple

Higher maintenance required, more complicated, higher product failures
