Day and Night Carbon Pre-Filter Blanket (46.0 x 11.5 x .25)

Air pollution accounts for 95% of all respiratory problems, including asthma, allergies, and bronchitis. When air from outside cannot circulate within a house, air pollutants begin to accumulate, leading to harmful health risks. Common indoor air pollutants include dust mites and particles, pollen, mold spores, tobacco smoke, chemicals, and gases.

A great way to help reduce respiratory problems is with a carbon air purifier filter. Carbon filters are the most absorbent filters available. This is due to their special filtration due to activated carbon. Carbon becomes activated when charcoal is treated with oxygen. This creates tiny pores in the carbon that absorb particles. The thicker the carbon, the more efficient a filter is, trapping tiny particles such as gases and odors, which ordinary filters are unable to capture. Most carbon filters come with a pre-filter, which absorbs larger particles such as dust and debris, allowing for greater efficiency of the regular carbon filter.

This Day and Night carbon pre-filter blanket fits whole house HEPA Jr. air purifier model P102-450. It is designed to keep the pre-filter more efficient by catching smaller particles such as some gases and odors. This makes the overall filter more efficient and able to last longer. This filter measures approximately 46.0" x 11.5" x .25" and should be replaced every 3 months for maximum performance.
