Dirty Air Filter that needs to be replaced

When was the last time you changed your Air Filter?

Have you checked out the air filters in your home recently? Often homeowners forget to check their air filters if they are not is a place that they don't see every day. Others just never think about it period. During the summer months, each air filter should be changed out every 30 days. Clean air filters will help prevent drain issues and will allow your system to be receiving and circulating cleaner air. Clean filters can also help people who have allergies and are sensitive to contaminates in the air.

Here are three easy things to do to make sure you're changing your filters every 30 days.

1. Set a reminder in your phone to change filters on the 1st of every month.

2. Take a picture of your filters so you know what size and what kind are best for your home. (If you're not sure what kind are best for your home, give us a call and we can help you out.)

3. Have a stock of clean air filters available so you don't have to run to the hardware store every month.

Types of Air Filters Available for Your Home

THE DIFFERENT TYPES OF AIR FILTERS
There are several types of air filters available classified by type and MERV rating. The MERV, or minimum efficiency reporting value, reflects to the ability of the filter to remove particles from the air, and it can range from one to 20, with a higher rating signifying better performance. The common types of air filters include:

Disposable filters: These inexpensive filters use flat fiberglass or polyester mesh to remove particles from the air. They typically have a MERV rating of one to four and are designed primarily to protect the HVAC system.

Reusable filters: Typically made of fiberglass or polyester mesh, these filters can be washed and reused. They have a MERV rating of one to four and are designed to save money over disposable filters, while primarily protecting the HVAC system.

Pleated filters: These filters use large pieces of fiberglass, polyester, or other synthetic materials that are folded into pleats, to increase surface area and remove more contaminants. They typically feature MERV ratings of five to 13 and can remove about 45 percent of air borner particles. High-efficiency versions can have ratings of up to 16 and will remove up to 85 percent of contaminants, but may be too large or restrictive for many systems. Pleated filters are relatively affordable, work in many systems, and provide significant air quality improvements over disposable or reusable filters.

Electrostatic filters: Electrostatic filters use an electric charge to attract particles as they pass through the filtering medium. They perform better than disposable filters or basic pleated filters, and they can have MERV ratings up to about 15. Electrostatic filters may not be compatible with all systems.

HEPA filters: With MERV ratings from 17 to 20, high-efficiency particulate air filters can remove up to 99.7 percent of contaminants, but they also require significant pressure to force air through, making them too restrictive for use in most HVAC systems that were not deigned them. HEPA filters are also more expensive than the other types.

WHICH AIR FILTER TO CHOOSE FOR YOUR HVAC SYSTEM
For the best indoor air quality, you should choose an air filter with a MERV rating of at least eight to 10. High-efficiency pleated, electrostatic or HEPA filters may remove more contaminants, but they may be too restrictive, too large or otherwise incompatible with your HVAC system.
