Regularly replacing filters will keep your home cleaner and help reduce dust and hair on floors, shelves, and more. If you suffer from allergies like a stuffy nose, itchiness, or breathing problems, it's even more important to change your air filter regularly. In addition, regularly changing your filter can improve the efficiency of your HVAC system.

Generally speaking, the best MERV filter rating for your home is between 8-10. These filters will capture most airborne particles and improve indoor air quality without significantly increasing your energy costs.

The Minimum Efficiency Reporting Value is a way to measure how efficient an air filter is. With a higher MERV value equating to finer filtration, this means fewer dust particles and other air pollutants can pass through the filter. Trightfilters offers air filters in MERV 8, MERV 11, and MERV 13 ratings.

If you’re using a higher MERV rated air filter, you should change it even more frequently.

Replacing the filter is simple. First, turn off the power to the unit. Locate the area with the air filter near the air supply and remove the plate. Then remove the spent filter. Check the airflow arrows and install the new filter. Make sure the airflow arrow on the filter is pointing toward the unit, then replace the cover. Finally, turn on the unit.

It depends on what kind of filter you have. If you use a disposable filter, it should be thrown away and replaced as soon as it gets dirty or clogged. If you use a permanent filter, you should clean it frequently. Generally, disposable filters are more convenient and less expensive.

You can buy air filters at a hardware store near you. For better filtration, buy from a trusted, high-quality filter brand like Trightfilters.

Air filters are made primarily of cardboard, supporting wire, and filter media. Depending on your filter needs, the filter media can be made of many different types of material, including fiberglass, polyester, cotton, and more.

Trightfilters offers MERV-8, MERV11 and MERV-13 rated air filters that capture and block 85% to 98% of airborne particles. Normal homes and businesses would benefit by just using MERV-8 filters. MERV-11 and MERV-13 air filters are mainly used for people who suffer from allergies or asthma that require higher air quality.

In terms of functionality, there is no difference between the three, as they all serve the same purpose: To protect your system from harmful airborne particles and improve air quality. Aside from the size difference, the air filter in the central HVAC system or exhaust vent is referred to as an "AC filter" or simply an "air filter", while the filter in the furnace system installed in your home is referred to as a "furnace filter".
