Honeywell Elite Allergen MERV 13 Pleated Air Filter (FPR) and Filtrete Micro Allergen Defense Air Filter MERV 11 are two of the best furnace air filters available in Canada. MERV ratings are used to measure the effectiveness of air filters in capturing particles. An oven filter with a MERV rating of 1 to 4 will keep out particles such as pollen, sawdust, carpet fibers, and dust mites. A MERV rating of 5-8 will keep mold spores, dust mite debris and dander away.
A MERV rating of 9 to 12 can remove fine dust, self-emitting particles and even droplets from the nebulizer. Higher MERV values of 12 to 16 can eliminate bacteria, smoke, paint pigments, and droplets created by sneezing and coughing. If someone in your household has allergies or asthma, you should consider a MERV 12 or higher. However, you should replace the filter regularly so that your oven doesn't burn out prematurely.
Oven filters with a MERV rating of 13 can remove smoke and other finer particles such as dust, pollen, dander, dust mite debris and mold spores. They also have an electrostatic charge and can capture even more particles in the air, including some viruses. Filtrete 20x25x1 AC Oven Air Filter and Filtrete 10x20x1 AC Oven Air Filter are two popular options for those who want to eliminate smoke and smoke odors from a home caused by cigarettes, fireplaces, and the kitchen. These filters can capture up to 99% of particles as small as 0.3 microns but require more energy from the oven fan as it pushes air through the filter.
If you allow the filter to clog, you can damage the heat exchanger or fan motor. Nordic Pure MERV 12 pleated air conditioning oven filters are a great choice for those who want to trap as much debris as possible in the air. They are one inch thick and come in a variety of sizes. AirX ALLERGY MERV 11 pleated air filter is designed with additional density to trap airborne allergens that can trigger allergy symptoms.
It's also good for blocking smoke and odors. The Aerostar Allergen & Pet Dander MERV 11 pleated disposable air filter is ideal for those with pets as it blocks a large amount of particles in the air, including pet hair and dander.
