Filters with a higher MERV rating should be replaced at least every three months to avoid airflow restriction and negative effects on oven performance. For example, if your air filter measures 10 ½ inches x 20 ¾ x 1¼ inches, the nominal dimensions are usually 11 x 21 inches x 1.MERV stands for Minimum Efficiency Reporting Values and is an industry-created standard that evaluates the efficiency of air filters. The MERV rating of any particular air filter ranges on a scale of 1 to 16, with filter rating 1 being the least efficient and filter rating 16 being the most efficient. If you notice air leaks on the sides after installation, you can use adhesive tape around the edges of the filter to achieve a tighter fit.
Glasfloss Z-Line 16x16x2 MERV 10 ZL oven filters excel when similar HVAC filters (heating, ventilation %26 and air conditioning) don't work well and, at the same time, offer an environmentally friendly design. Glasfloss GDS 16 x 16 x 2 double-ended disposable oven filters are excellent for protecting your HVAC (heating, ventilation, air conditioning at 26%) and removing dust, dust mites, pollen and other contaminants from indoor air. Glasfloss Z-Line MR-11 16x16x2 MERV 11 oven filters are an economical upgrade to standard pleated air filters and are excellent when similar HVAC filters (heating, ventilation %26 and air conditioning) don't work. The odor remover filter uses a carbon filter medium to efficiently remove household odors without reducing air flow.
