Asthma and Allergy Sufferers may find remarkable relief  from Triggers.

A properly ventilated home with HEPA filtration of all intake air can become “a Sanctuary of Relief and Comfort” by keeping 99.97% of pollen and other asthma and allergy triggers outdoors even during high pollen season.

Our Type 1 Honeywell HEPA Filter will remove 99.97% of the bad stuff from the fresh air delivered into your home. 24/7/365

HEPA filters are incredible. Laboratory grade laser particle counter field tests in Collier County have demonstrated particle reductions from 1.200,000 (that’s 1.2 million) particles per cubic foot to 970 particles per cubic foot with a single pass through a Honeywell HRF-11 HEPA filter. During an everglades fire, particle counts in Naples exceeded 16 million particles per cubic foot of outdoor air.

A home can become a sanctuary of good Health with the super clean air that passes through this Honeywell HRF-11 True HEPA filter. Outdoor pollen, mold spores, red tide particles, agricultural chemical aerosols, bacteria, viruses, PM 2.5,  soot, even smoke will be removed from the air stream before it enters the breathing zone. Just like the clean, crisp mountain air we had 50 years ago. Inhaling deeply can feel really good again.

The SmartVentilation Type I HEPA filter kit is an easy replacement/retrofit for any air intake filter over a 4″, 5″, or 6″ round air intake opening on an exterior wall. Kit includes a Honeywell PRF-11 HEPA filter, mounting bracket, stainless steel fasteners, paintable ABS cover and wing nut cover fastener. It is an option on the Daisy Ductless and the Red Zephyr radon mitigation/fresh air systems.


If you add a CO2 (carbon dioxide) control to  your HEPA ventilation system to limit CO2 to 600 parts per million, you can enjoy the remarkable, additional benefits of improved cognitive function and better sleep described in recent research from Lawrence Berkeley National Laboratory and the Harvard TH Chan School of Public Health
