Indoor air quality is important to people’s health at home or in any other setting. When air quality is not good, there can be negative effects on health. Our discount furnace filters come in a variety of sizes and types, including 12 x 12 x 1 filters. Here’s what you need to know about that size filter and its benefits.
Technical Specifications
Filters are categorized based on how much and what they filter from the air. The categorization system is know as MERV, which stands for Minimum Efficiency Reporting Value. Here are some typical MERV levels for filters, along with the corresponding categories in our filters.
The MERV 8 (DUST) type of filter removes numerous allergens and particles from the air. It does not do so to the same extent as more high-end HVAC filters, but it is also more effective at cleaning the air than low-end filters. The MERV8 filter removes pollen, household dust, and pet dander from indoor air.
The MERV 11 (ALLERGY) type filter is a level up in effectiveness from the MERV8 filter, as it filters more from indoor air. The particles it filters include pollen, dust, pet dander, mold spores, car fumes, and smog.
The MERV 13 (HEALTH) type filter is another step up from the MERV8 and MERV11. This is because of its greater ability to filter out more allergens from indoor air. Those include pollen, pet dander, dust, dust mites, bacteria, viruses, mold spores, various types of smoke such as tobacco smoke, smog, car fumes, and others.
We have various choices available in 12 x 12 x 1 air filters, including Basic, Dust, Allergy, Health, Odor and Washable. This broad range of options suits a variety of households and specific needs for filtration.
The 12 x 12 x 1 filter is simply, quick and easy to install. Here’s how:
First, turn off the power that is going to your furnace before changing the air filters. Remove the old air filter from the HVAC system, and discard that filter. When placing your new air filter into the grille, make sure the arrow on the side of the filter is pointing toward the furnace. Turn the power and furnace back on, and verify that everything is working correctly.
Indoor Air Quality in Schools
One of the settings where indoor air quality is so important is schools. But in many schools, air quality leaves a lot to be desired. And a study by the National Center for Educations Statistics in 2014 showed that the average school in the United States is 55 years old. About 25% of the schools need extensive repairs, and about 50% have poor indoor air quality. When air quality is bad, students’ productivity and learning suffers, so air quality needs to be addressed and improved.
Whether at school or at home, air quality can be improved by using specialized filters and monitoring air quality. Get started today with our discount furnace filters.


If you use the lowest rated fiberglass filter you can spray the filter with recharge adhesive. I think in all fairness you should address this for the average consumer who does not know that it exists. You could also explain how to use it. It also increases the efficiency of the filter.
