Dust & Pollen Filter Screen for Allergies & No-See-Ums
Standard window screens are designed to stop mosquitoes, not microscopic particles. Pollen grains and fine urban dust pass straight through an 18x16 weave. For allergy and asthma sufferers, opening the window often means trading fresh air for a flare-up. The MBORMC FD04 dust and pollen filter screen solves that — a high-density micro-woven mesh captures pollen, dust, and soot while still allowing airflow.
It also blocks no-see-ums — the tiny biting midges that pass through standard screens in coastal and wooded areas across the US [citation:2][citation:11]. Custom-cut to your window frame with a zero-gap magnetic seal, it is the fine mesh screen for asthma and allergy sufferers who refuse to keep windows closed all season.
Why a Standard Screen Does Not Stop Pollen or No-See-Ums
A standard insect screen has an 18x16 weave — roughly 1.2 mm openings. That stops a mosquito but does nothing for pollen grains (10–100 microns) or no-see-ums, which are small enough to pass through standard mesh [citation:2][citation:3].
The FD04 uses a high-density micro-woven mesh with a tighter weave. It captures the particles that trigger allergies and the tiny biting insects that make a patio unusable in coastal Florida, the Gulf Coast, and wooded areas. US screen manufacturers now offer similar fine-mesh products specifically for allergy and no-see-um protection, and the FD04 delivers the same filtration with a custom-fit magnetic seal [citation:2][citation:3][citation:8].
Technical Specifications
Engineered for American allergy seasons and no-see-um country.
Where the FD04 Works
Designed for the American homes and regions where allergies and no-see-ums hit hardest.
Allergy Sufferer Bedrooms
Sleep with windows open during pollen season. The FD04 filters the pollen that triggers morning congestion, so you breathe easier overnight.
Coastal & Wooded Areas
No-see-ums are a fact of life in Florida, the Gulf Coast, and wooded regions [citation:2]. The fine mesh blocks them where standard screens fail.
Urban & Near-Road Homes
Captures fine dust and soot from traffic before it settles on windowsills and furniture. Less cleaning, cleaner air.
Asthma & Severe Allergy Homes
For households where outdoor air quality directly affects breathing. The FD04 is a passive first line of defense before indoor purifiers.
