The furnace in your home circulates air throughout the house to keep the temperature comfortable. It has a filter to keep dirt and dust from being blown around the home while the furnace or air conditioner is on. Since this product comes in many varieties, you may not know which one works best for your home. Here are the facts about various HVAC filters to help you make a better choice with your next purchase.
- Washable Filters
A reusable filter is an excellent choice if you want an environmentally friendly option. These products cost more upfront but last many years, so the price is less than purchasing new filters every few months. Take care when you clean the filter and ensure the product is dry before inserting it back into the HVAC air filter housing so that mold and algae don’t grow and blow through your home.
- HEPA Filters
A high-efficiency particulate air filter is ideal if someone in your home suffers from allergies or lung ailments. These filters capture over 97% of the dust, mold and other allergen particles from the air, preventing them from circulating the house when the HVAC runs.
- Pleated Filters
A pleated fabric filter is the standard filter designed to fit most home air systems. The material is usually either cotton or polyester, folded back and forth to give it an accordion appearance. The filter material has a greater surface area this way, so it keeps more dirt and small particles out of the air. These filters are one of the least expensive options on the market, and you may need to replace them as often as every 30 days.
There are many different options when it comes to choosing a furnace filter replacement. Depending on your needs, you may find a washable, HEPA or pleated filter works best for your home.
