Air Filters: What Are the Key Do’s and Don’ts

Air filters are essential for the efficient performance and longevity of your HVAC system. Regular filter changes will promote good indoor air quality as well. If these filters are dirty, not only will your equipment perform poorly, but it will also be at risk of early failure. 

Read on to learn the do’s and don’ts of air filters. 

Do’s

Check MERV Ratings

HVAC filters come in a wide selection of styles and levels of quality. When purchasing a new one, do make it a habit to check the product’s Minimum Efficiency Reporting Value (MERV) rating. This rating tells you how many or how fine an air filter can catch. It will also help you determine how frequently the product needs to be replaced. 

Change Filters Regularly

It’s a good idea to set reminders on when you need to clean or replace your air filters. Keep in mind that dirty filters can restrict airflow in your HVAC system, making it inefficient, work harder and consume more energy. 

Choose a Filter Suitable for Your Needs

Do you have pets at home, or is someone from the family suffering from allergies or asthma? Consider these things when picking out a filter for your HVAC system. How many you are in the household also affects what kind of air filter you need and when you need to replace it. If you are unsure which product to buy, you can also consult your air conditioning installation technician. 

Don’ts

Not Turning Off Your AC Before Replacing Filters

Before replacing air filters, make sure to turn off your air conditioner completely. It is not enough that you only turned off your thermostat as it is not safe enough. Disconnect the AC before changing air filters to avoid getting electric shocks from wirings. 

Changing Your Filter Even if You Don’t Know How to Do It

Never try to change air filters if you do not know how to do it. It’s best to contact a local technician to help do the job for you. Doing so will prevent unnecessary damage and ensure the filters are installed correctly.
