Rabbit Air BioGS SPA-582A (covers up to 780 sq. ft.) Ultra Quiet HEPA Air Purifier - Low Maintenance - Washable Filters!

I have problems with airborne allergens and with asthma. I have spent nearly two thousand dollars on different air cleaners over the past ten years. They all proved to be ineffective, noisy, ugly, and/or overpriced. The Bio Fresh works for me. None of the others did. I enjoy the several different modes of cleaning available. It is an attractive machine that fits nicely against a wall. Everything about it is well thought-out. It is well worth the money. I just purchased my second Bio Fresh air cleaner and it was delivered earlier than expected. It has helped my breathing more than all the antihistamines, inhalers, and all the other machines combined.

Let me start off with the negative points, but qualifying that by saying this is a positive review;

- There doesn't seem to be much difference between the 582A and the lower-coverage 421A, except for the calibrated fan speeds. If you don't intend to run the unit "full-tilt", or if noise is a concern, you're better off saving the extra 70$ and buying the 421A.

- The "auto" mode seems to be of dubious value, and will significantly reduce the coverage area of the unit, because it relies on the on-board sensors to adjust fan speed, and they can't sample air quality over the entire advertised coverage area unless the unit is on very high. You can test this yourself by hitting the "turbo" button -- the dust/odor sensor will spike as the unit pulls in more air. You'll be better off to manually set the fan to the highest setting that you find acceptable (noise-wise), and purchasing multiple units for coverage. See my previous comments about the 421A.

Before buying the Rabbit Air BioGP 582A, I bought three other units.

The new Oreck Tower Pro XL was first. It was an amazing product, made the entire area smell fresh and the turbo mode is powerful like a rocket. Why did I return it? After a month or so, it started to *hum* in an annoying oscillating way.

Then I tried the Friedrich C-90B. The ugliest unit by far, looks like it was designed in 1970. But it worked great. Why did I return it? After a week it started to *rattle*, the fan blades hitting.

Then I tried the Alen A375. I was impressed, it had a low-tech remote control, seemed advanced compared to the Friendrich but still a dull white color. Why did I return it? It was weak, didn't purify the air or deodorize, and the fan vented air straight up.

So then I found out about this Rabbit, and purchased one. It is by far the most impressive looking unit, Lighted display, high-tech remote, beautifully designed. The good news is...Read more
