Rabbit Air Purifier Review: Model BioGS 421A Test Results

Retail Price: $329-399

OVERVIEW: The Rabbit Air Purifier line has several models but we'll start our review with their most popular, and affordably priced BioGS 421A. The Rabbit Air Air purifiers all have a good range of filters including HEPA. It was designed by Mitsubishi and my only complaint about design is the fact that the unit shakes or vibrates slightly when the fan speed is on high.

Rated for 600 sq. ft. their suggestion for allergy sufferers is 300 sq. ft. That's because you want to completely clean all the air in a room several times an hour for effective allergen removal. Let's look closer at some of what's inside this purifier.

4 Stages of Filters Reviewed

The Rabbit Air Purifier 421A model has a 4-stage filtration system with a few added technologies for germs and viruses:

Stage one is a washable pre-filter that has nanotechnology silver coated onto it. This silver coating has some anti - bacterial properties.

Stage two is the HEPA filter with which has an added treatment to reduce germs. This won't do as thorough a job on germs as Ultraviolet light so much as it will keep germs from growing on the HEPA filter itself.

(Note: Whether these treatments have an effect greater than Ultraviolet light, or UV and Titanium Dioxide is in question. We plan on doing some tests at the University here to try and determine the effectiveness.)

Rabbit suggests changing the filters every 18 months (if run 12 hours a day) however I don't find that filters will last more than 9-12 months. the filters will run you about $46 for HEPA and $30 for the carbon plus tax and shipping.

Stage 3 is a nice activated carbon filter to trap gases and odors. It can be washed several times, but I would be wary of doing so because charcoal absorbs water and mildew may develop. Make sure you dry it out completely and hit it with a hair dryer to make sure.

Stage 4 is negative ions - which are both good for your health and can go out into the room to purify the air, kill mold, and can eliminate some odors.

Rabbit Air Purifier Conclusion

The Rabbit Air Purifier is one of the better units on the markets, with a wide range of filters and technologies for helping allergies, odors, and other air problems. I would have liked a bit more germ and virus protection (like UV) other than the nano-silver and HEPA treatment but at least they thought of it. My otehrconcern is the expensive replacement HEPA and Carbon.

For general house cleaning and allergies I would recommend it. if you want to spend less, or get something with more technologies see the comparison video below...
