Refill for Safe Home Electrostatic Return Grille Filter,4 Pre-Filters and Carbon Filter

Use with frame (not included) in return vent air duct. Electrostatic return air grille filter. No electricity required. Purify air going into return cold air ducts. Add furnace air filter system replacement for floor or wall cold air returns. Replace 20 by 20 by 1 inch allergy air filter with this twin furnace filter filtration system . Safe Home air purification system has four (4) replacement electrostatic dust and allergen filters and one high density carbon filter to remove odors and gasses from home or business. Always check with your HVAC technician before changing from your current furnace filter

Note: These filters are not returnable once removed from packaging. No metal frame is included. Prior to ordering, please make sure your return air grille has a filter frame that will hold this filter system.

Use Safe Home ™ system furnace filters to trap odors, allergens and chemicals in your furnace filter instead of in your nose and lungs. Sealing homes for energy savings increases concentrations of gases that can cause asthma and allergies. HEPA filters do not stop formaldehyde that is commonly released from household products such as furniture, paint and cleaning agents.

Easily used: remove or open air return grill filter holder. Insert high density carbon filter into the cold air return and then the white air filter. Close.

Safe Home Air Purification System Features:
  • Captures up to 95% of the common household allergens that can cause sneezing, sniffling and other allergic reactions with replaceable pre-filter.
  • Eliminates or reduces odors from animals, paint, food and more via the second high density carbon filter.
  • Formaldasorb within the carbon filter traps harmful gases such as ammonia and formaldehyde.
Installation: No furnace duct modifications are required. No electricity is required. The Safe Home filter system replaces the one inch washable air filter or disposable air filter already in use in your home's cold air return grille filters. First, remove old air filter, Next, insert the carbon filter into the duct work behind the grille air filter slot..Then install the second white furnace filter in the return air grille filter slot.

You now have a two step filter process. The white pre-filter captures dust, pollen and other particles. The air then filters through the second carbon filter that captures gases and odors. This two step system reduces pollution significantly in your home, clinic or other business.

For the best pollution control, change the carbon air purifier filter at least once per year. The white allergen filter needs replacement at least every three months. More polluted environments may require more frequent changes of both filters.

Safe Home Air Purification System includes 4 pre-filters that fit the cold air return grille slot and one carbon filter that fits into metal ductwork behind the grille. Each one inch white pre-filter is pleated and has a continuous metal diamond pattern on all pleats. Filters are made to fit into a metal return air frame. Always install so that return air flows through the pre-filter first.

Available Sizes Include: 14X20X1, 14X25X1, 16X20X1, 16X25X1, 20X20X1, 20X25X1, 24X24X1

Safe Home filters are the only one inch home filters for return grilles of air HVAC furnaces that trap allergens, odors and harmful chemicals without requiring a modification of the furnace duct work. Safe Home filters remove allergens such as dust mites, pollen and mold spores.

NOTE: These filters will NOT filter out carbon monoxide, radon gas or carbon dioxide. We recommend installing carbon monoxide monitors on every level of your home and in or near all sleeping areas. Test units regularly. Replace batteries at least annually.
