Our air purifiers (including auto air purifier) utilize proven technology such as large beds of activated carbon, state of the art  HEPA filters, and optional UV lights to remove dusts, mold, pollens, allergens, viruses, bacteria, and chemicals from the air you breathe. Our air purifiers are recommended by allergists & environmental doctors internationally, but are made in the USA!  We carry a full line of Everpure, Multipure, & Hurley water filtration products (including whole house & shower filters), which are all rated by the NSF for taste, odor, chlorine reduction, many other chemicals, and particulate reduction. We can help you find the HVAC solution that is right for your home or business; everything from a simple 1" filter to more complex commercial / industrial applications (including HEPA), and get you a great price too.  Many of our products will fit into GREEN purchasing programs or will help keep our environment safe.

The Series 400 Air Purifier is the largest of our free standing room air purifiers.

Rated for up to 1000 square feet, it uses a large carbon bed  to remove chemicals, fumes, odors, perfumes and a safe HEPA to trap  particles down to 0.3 microns in size.

The UV light option is available to help disinfect your indoor air of germs and virus. Units are used & recommended by allergists & environmental doctors nationwide.

All metal construction of the cabinet makes this a sturdy, long-lasting product, and we use either a no-odor powder coat finish or you can order in an all stainless steel cabinet!
