EnviroMax^® Filters is a part of the Air Purification of Houston family. We are a family owned and operated, licensed HVAC business, established in 1979 with the primary purpose to provide superior products and services for any indoor air quality problems. In 2003 we developed and received a patent for a unique filtration system that allows air conditioning systems to filter out 98% of dust particles at 5 microns.

There are several facts about this air filter that make is so effective:

1. This unique filtration system is so effective and efficient that the filter doesn't have to be replaced for one full year! The 4 inch thick pleated filter has six times the surface area and the same media thickness of a conventional air filters. This allows more dust to be trapped without compromising air flow.

2. Since the air filter is capturing more dust particles and smaller particles, it is keeping them out of your duct work and, more importantly, off your evaporator coils. A/C contractors will tell you, cleaner coils and less dust will lengthen the life of your system.

3. The cost of the Enviromax^® filter is no more than conventional filters that are replaced monthly. The EnviroMax^® cost around $5.00 a month. Not much for cleaner air that will reduce dust particles and allergies in the home.

4. Enviromax^® filters are convenient. We will remind you when your filter is due to be replaced. No more wondering when your filter is due to be replaced, what the size is, where to buy it, or even when to go get one. We will send an e-mail reminder when it is due to replace and you can conveniently reorder online or by phone.
