Filtrete™ Air Filters and Filtrete™ Room Air Purifiers for Easier Breathing
If you want to improve the air quality inside your home, look no further than to Filtrete™ air filters and Filtrete™ air purifiers at Lowe’s. You’ll always find the selection you need at the right price, including the most popular models, such as Filtrete™ smart air filters, 3M air filters and 3M furnace filters, as well as the 3M 2200 Series Filtrete™ filter. We even stock Filtrete™ smart air filters, which have a special Bluetooth-enabled sensor to help you track filter activity using data from your home’s HVAC system.
Installing new air filters regularly is an important part of heating, ventilating and air conditioning maintenance. While some air conditioners (A/C) have reusable filters, others use disposable filters that you can simply replace with no cleaning.
Filters come in different sizes to fit different A/C units. Filter sizes specify filter dimensions in inches — such as 20 by 25 by 1 — with the numbers referring to width, height and thickness.
Shop in store or get your air filters delivered through Lowe’s today. You can even select our convenient and cost-effective subscription option so you never have to wonder if it’s time to order new filters again.

Frequently Asked Questions
Q: What kind of air filter is the best?
A: The best HVAC air filter is a pleated filter with a minimum efficiency reporting value (MERV) rating of 8 to 13. Pleats catch more particles and allow better airflow. A higher MERV rating indicates that a filter traps more particles. However, a filter with a MERV rating that’s too high can restrict airflow too much and cause excess wear on your HVAC equipment.
Q: How often should I change my air filter?
A: Change a pleated HVAC filter every 90 days and change basic, spun-fiberglass filters about once a month. Depending on the conditions in your home, such as dust levels or the presence of pets, you may need to change your filter more often. If you notice the filters seem particularly dirty when you change them, consider replacing them more often.
Q: What are air filters good for?
A: Air filters remove many contaminants and allergens from the air. They also protect your HVAC system from the damage debris can do as the system circulates cool or warm air. You can find filters that trap dust, pet dander, bacteria and more. Learn about how filters work and their benefits by reading Reduce Allergens in Your Home.
