Product Description

BMT AllergyGuard NanoScreen™ delivers superior filtration performance. The only product that screens out such fine particle sizes. BMT Allergy Guard allows people to enjoy fresh air without worrying about pollen, pollutants, or other fine particles from entering their home or office.

With our patented NanoScreen™ technology, BMT Allergy Guard creates a force-field around the home or work environment that allows the air to flow but blocks out the allergens and fine dust and pollution particles.

Make Allergy Guard a Part of Your Health & Wellness Plan

Our purpose is to promote health and wellness across North America and our goal is to empower millions of people that suffer from allergies to turn off the air conditioners and open their windows and doors and let the fresh air flow into their homes and work environments.


1 mm = 1000 microns (μm) (also called micrometers)
1 micron (μm) = 1000 nanometers
1 nanometer (nm) = 1000 times smaller than a micron
1 nanometer (nm) = 1 billionth of a meter

Allergy Guard can allow you to enjoy fresh outdoor air without the allergies! Window filter screen blocks pollen, dust, pollution, ash, hair, and other particulates as small as 300 nanometers while standard window screen only blocks particles that are 2,000,000 in size.
