How to Choose the Right Air Filter

Spring can have some beautiful weather, but it can also bring dust, pollen, and allergens into your home. One of the best ways to protect your West Chester area home from poor air circulation is to change the air filter in your HVAC system often. Learn more about air filters and our MoreVent recommendations for regular maintenance.

What does the filter do?

Your air conditioning system requires a filter to catch any dust or other particles in the air before it enters the evaporator of the machine. If the filter becomes too dirty or clogged with debris, then airflow will be restricted, causing the unit to work harder to keep up and increasing your energy bills. Maintaining a clean filter will keep your air quality higher and prevent costly repairs to your HVAC system.

How often should I really change it?

Your basic 1” filters need to be changed monthly, especially during seasons of high usage. Be sure to follow the recommended filter options from your manufacturer’s guide and get accurate measurements for your machine. When purchasing a new filter, look for one with a sturdy design of pleated material with internal wire structure support and outer lattice and edge support.

Compare MERV ratings

The Minimum Efficiency Reporting Value (MERV) is a measurement to compare the efficiency of air filters. The MERV rating scale ranges from 1 to 16, with the higher ratings being the most efficient. A high-rated filter will not only remove more particles and dust from the air, but it can also remove smaller particles. You can ask a MoreVent technician about the MERV rating of your filter at your next tune-up.

Disposable isn’t the only option

Although disposable filters are usually most common, another option is a media filter. This type of filter is installed by a MoreVent professional and needs maintenance every six months. They can be more expensive, but they are generally more efficient, filter the air more effectively and require less work for you as the homeowner. Check with your MoreVent technician if a media filter would be a good option for your household.

If you have any questions about the air filter on your HVAC unit, you can always call MoreVent at (610) 444-3333 or schedule a visit online to check on your unit and its filter.
