How Often Should You Change Your Merv 11 Furnace Filter?

The basic recommendation for oven filter replacement is every 3-4 months for MERV 8, every 6 months for MERV 10 and 11, and every year for MERV 16. However, experts suggest changing it once every 30 days if your air filter is made of fiberglass filters, which are of relatively low quality. On the other hand, expensive pleated filters can work well with a replacement once every three months or six months. You must change the filter at least every 90 days. A general rule of thumb for pleated air filters (such as those manufactured by FilterBuy) is to replace the filter every 90 days.

As the filter traps more dirt, dust and allergens from the air, its efficiency decreases. Find out below if you should replace the filter more often. The more animals that live in your home, the shorter the filter will last. Having multiple animals means you need to change a one- or two-inch filter every month, a four-inch filter every two months, and a five-inch filter every three months.

In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months. This may vary depending on the location of your home (e.g. dry and dusty climates), if you have pets, and the age of your system and equipment. If you have pets in your home, you should consider changing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, we recommend changing the filter every 20 to 45 days.

Usually, vacation homes or vacant homes that don't have much use can expect to change filters every 9-12 months. The general consensus is that the more you use your home, the more you need to change the air filter. You may not have realized that your oven filter needs to be changed because oven filters are not needed in all HVAC systems. So it's best to be safe and change the filter more often to make sure your oven doesn't go bad when you need it. Just be careful not to confuse Honeywell oven filters with their HEPA air filters for purifiers, which last much longer.

In general, the ideal MERV filter for your home depends on your needs, in addition to what you have in your home. The only type of filters that trap allergens and spores are HEPA, or high-energy particulate air filters. Simply replacing a dirty filter keeps your system running efficiently, prevents system breakdowns, and can extend the life of your HVAC system. A clean filter is necessary to prevent dust from passing through the HVAC system, where it can accumulate in the internal coils of the air conditioner and reduce the efficiency of the unit. On the other hand, if you use your HVAC system almost constantly, you'll need to change the filter every few weeks (especially if you use fiberglass filters).

The strongest filters are reusable, usually with metal frames, and can be cleaned according to the manufacturer's instructions. Simply put, if you have poor air quality outside and inside your home, you'll need to replace the air filter more often. No two houses are alike, so despite guidelines, you may need to change your boiler filter more often than your neighbor. In addition to keeping the HVAC system free of contaminants, oven filters also help clean the indoor air you breathe. But how often do you need to change the air filter? How often do you need to change the oven filter? Well, it depends.
