5PK Replacement Heavy Duty 18x18x1 Aluminum Electrostatic Washable Air Purifier A/C Filter for Central HVAC Conditioner Furnace Systems

These filters are brand new high quality replacement parts by LifeSupplyUSA, exclusively for sale by LifeSupplyUSA. Without any modifications, these aluminum electrostatic heavy duty filters will operate and replace any disposable or existing air conditioning/heating filter. These filters help purify the air of dirt, dust, pollen, pet dander and other allergens which can help reduce the discomfort and irritation of allergy sufferers, itchy/watery eyes and sneezing. As an electrostatic charge is generated by the air flowing through the filter, contaminants are attracted like a magnet and held by the static charge, without the release until washed (no electrical connections needed!). It is recommended filters be washed at least every 1-3 months, depending on usage and air quality. To clean, remove filter, vacuum/use low pressure hose on both sides and rinse with water. For the removal of tough grease or smoke, you may have to wash with a mild house-hold detergent such as hand wash or dish detergent. Before re-installing into your system, be sure to let the filter dry. Mesh design makes the filter easier to wash and rugged aluminum frame, prevents corrosion or rust.
