The Safe Home™ Duo4
looks different because it is different. Safe Home's filters
are the only home
air replacement filters that capture allergens, odors, and harmful
chemicals. The Duo4 features a superior design with self sealing edges
for maximum effectiveness at capturing allergens, odors, and chemicals
from the air in your house. Use for furnace filter slots, temporary
needs, or custom sizes in air return grills. The Duo4 replaces any 4"
thick home air filter
in any location and can last up to 3 months. How does the Duo4 work?
This dirt and chemical air filter uses 300 grams/sq. ft. of 50/50 activated carbon and potassium permanganate based FormaldaSorb™ to trap gases, odors and chemicals including formaldehyde, benzene, toluene, ammonia and ozone. These chemicals
come from cleaning
chemicals, paint, particle board, and other household items. No other
filters are as effective at the Duo4 at this removal plus removing dust mites, mold spores, and pollen that can trigger allergies and asthma. Safe Home Duo4 Filter Features:
- Dimensions: 20,75" x 21" x 4"
- Captures up to 95% of common household allergens
- Eliminates odors from pets, paint, cooking, and more
- Uses high density carbon and advanced compounds
- FormaldaSorb™, a patented potassium permanganate product plus
the activated carbon in the second layer of the filter trap gasses that
can cause health issues.
Highly effective and affordable.
Twin filter pad: MERV 8 polyester white ASHRAE rated allergen filter plus an industrial chemical and odor filter, i.e. the activated carbon filter pad. Install so that the air flow first goes through the allergen filter side and exits through the darker, chemical and odor filtration media.
