The MERV 8 20x25x4 air filter is a standard-capacity pleated panel filter that is suitable for residential applications, but is also suitable for heavy, commercial, industrial, pharmaceutical and other industrial applications where high dust retention is required. The filter frames are made of beverage cardboard, which remains resistant to moisture and temperatures up to 200° F. Quality filters that work well for us, the price is usually better than competitive prices, so there are usually online coupons available to save even more. When selecting an air filter, it is important to take into account the MERV rating. A MERV 11 offers excellent protection, allowing the heating and cooling system to flow effectively while still providing superior filtration.
This helps to save energy costs and reduce costly repairs. However, if you have pets, children, or allergy sufferers in your home or business, it may be beneficial to opt for a higher MERV rating and replace filters more often in order to maintain higher indoor air quality. When creating a filter with this tool, it is important to use the “real” size of the filter as shown by the measuring tape and not a nominal filter size. If you have purchased the wrong size filter, many companies will do their best to get you the right one.
