How to Choose a Customized Filter

Even without a customized filter, the A3 air purifier can trap and reduce most airborne pollutants, allergens and odors. However, Rabbit Air developed a series of customized filters to target specific areas of concern for our customers. These custom filters can enhance the overall system effectiveness on allergen, odor and chemical removal.

Germ Defense Filter

Effectively traps and reduces airborne bacteria, mold spores and particles that carry viruses.

Toxin Absorber Filter

Traps and reduces volatile organic compounds (VOCs) and other chemicals.

Pet Allergy Filter

Traps and reduces pet dander and pet odors.

Odor Remover Filter

Traps and reduces odors from pets, cigarettes and cigars, cooking and mildew.

I recently had my hardwood floors refinished and the smell was overwhelming. I purchased the A3 air purifier with the special VOC filter and in less then 24 hours the toxic smell of 1000 sq ft of polyurethane was gone and I could breathe again in my home. I highly recommend both the A3 air purifier and the special VOC filter.

Experience with replacement filters

The replacement filters I purchased arrived quickly and were super easy to install. The packaging was great and the instructions for installing them were clear and easy to follow. Further, they made an immediate difference in the air quality of my home office. My unit does a great job of eliminating cigar smoke odors.

FANTASTIC Air Purifiers

We bought 2 units just over one month ago and we are extremely satisfied with both units. We have the SPA-1000N and the SPA-780. We clearly noticed that each unit cleared the air throughout our unit which is approximately 1588 SF. The air smells cleaner and fresher and each unit immediately speeds up if they sense anything in the air, whether it is smog or cooking odors, or even putting clean sheets on the bed, We, no longer wake up to snuffed noses. They are truly quiet, to the point where I have to check if air is actually flowing, which it always is. If you are looking for quality air purifiers look no further than RabbitAir as they are worth every penny. Treat yourself with clean air to breath and a better life to live.
