For Merv 8, 11 and 13 filters, we recommend that you change the filter at least every 3 months, however, changing the filter every 2 months provides better filtration, providing healthier and cleaner air in your home. However, experts recommend changing it once every 30 days if the air filter is made of fiberglass filters, which are of relatively poor quality. On the other hand, expensive pleated filters can work well with a replacement once every three months or six months. Filter types are determined by their MERV rating.
A MERV rating, Minimum Value of Efficiency Reports, measures filtration effectiveness. The higher the MERV ratings, the more effective the filter will be at not allowing particles in the air to pass through it. We offer MERV 8, 10, 11 and 16 filters for sale in our office and can also order special one-off sizes. The MERV rating also generally determines how often the oven filter needs to be changed.
You should have a clean filter, MERV 8 filters should be changed every 3-4 months, MERV 10% 26 11 filters every 6 months and it's a good idea to change MERV 16 filters every year. In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. That may change depending on the location of your home (e.g. EJ.
dry and dusty climates), if you have pets and the age of your system and equipment. If you have pets in the house, 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. Vacation homes or vacant homes that don't have much use can usually wait 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.
If there is only a thin layer of dirt where you can still see the filter underneath, then you probably don't have to change the filter. In addition to filtering particles filtered by MERV 8 and 11, the MERV 13 can filter kitchen smoke, smog and virus carriers. How often the oven filter needs to be changed will depend on the type of material and the efficiency of the filter you select. In general, low-MERV filters can last longer because they don't collect as much particulate matter as high-MERV filters.
As seasons change, pollen and other seasonal particles can quickly clog a disposable filter, even if it's a four-inch filter. Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings. When you remove the air filter from the air handling unit, if you hold it close to a light source, you can see if the filter is dirty or clogged; if you can't see the light through the filter, it's definitely time to change it. In general, filters with a MERV 16 rating or lower are considered HVAC system grade filters for residential, commercial, and general hospital use.
It's a general recommendation to change your home's air filter every 30 days when using less expensive fiberglass filters. Air filters typically have a MERV (Minimum Efficiency Report Value) that determines the type and size of contaminants against which the filter will act. MERV (Minimum Efficiency Report Value) is a rating that tells you how effective an air filter is or, more specifically, how well it can trap particles in your home's air. However, the smaller the appliance used for cooling, the small space usually comes with smaller filters, so you may need to change the filter as often as a filter in a larger home.
In general, the ideal MERV filter for your home depends on your needs, in addition to what you have in your home. .
