The Power of Baking Soda

Baking soda has been used for decades to eliminate lingering, offensive kitchen and household odors. NaturalAire Odor Eliminator with Baking Soda air filters utilize its incredible power for exceptional HVAC filters. The special qualities of baking soda gives it powerful antiseptic properties. Since baking soda is a safe, naturally occurring substance you can feel secure with the knowledge that the air in your home or office will be fresh, clean, and free of offensive odors.

Durability You Can Trust

The NaturalAire Odor Eliminator with Baking Soda air filter’s frame is bordered with 1 inch of recyclable, clay-coated, moisture-resistant molding for long-lasting durability and increased efficiency. The filter’s sturdy, wire-backed and pleated synthetic media stands up to the elements and to the temperature shifts put out by your HVAC system. Having a reliable NaturalAire Odor Eliminator with Baking Soda air filter lets you and your family breathe freely without worrying that your HVAC is under-performing due to an inefficient air filter.

Change Filters Regularly

The U.S. Environmental Protection Agency (EPA) recommends that air filters for household HVAC systems be changed regularly. The NaturalAire Odor Eliminator with Baking Soda air filter carries a 90-day lifespan, and its pleated construction has a larger surface area for catching impurities and odors, providing fresh air for the longest possible amount of time before suggested replacement. Air filters changed regularly maintain sufficient airflow and keep HVAC units running at peak efficiency, which keeps your air clean and fresh longer.

Measuring Your Air Filter

Choosing the right size filter is important for keeping your home's air clean. An improperly sized filter will bend if it is too large or fail to catch impurities if it is too small. To determine the dimensions of your filter, measure the width, height, and depth separately in inches of the space where the filter will go in your HVAC system. This will give you three measurements. For instance, a filter with a width of 20 inch, a height of 20 inch, and a depth of 1 inch will give you a filter with dimensions of 20 x 20 x 1. Correctly measuring your filter will help you properly choose the right filter for your home.

    About MERV, MPR and FPR Rating

    The three rating systems were created by different organizations. MERV is the domestic and international Industry Standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. The other two rating systems were created by 3M and The Home Depot, but all are rating the same filter.

    MERV Rating (Minimum Efficiency Reporting Value): As you have already learned, the MERV Rating is the primary rating system used in the industry, both domestically and internationally. Established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, MERV rates a filter’s ability to capture and hold particles and pollutants.

    MPR (Micro-Particle Performance Rating): MPR Rating is a rating system developed by 3M. It rates the manufacturer’s Filtrete product line and their ability to capture airborne particles smaller than 1 micron.

    FPR (Filter Performance Rating): FPR Rating is a rating system developed by The Home Depot for brands sold through their stores, including Honeywell. It utilizes a color code and number scale (4 to 10) that closely resembles the MERV rating.

Be sure you have measured your existing filter before placing an order, some manufacturers undercut filters so you should never base it off the label. Exact/custom filters are not eligible for returns or exchanges. Manufacturing tolerances of plus 0, minus 1/8" will be observed on overall width and length of filter. Picture is used as a reference, sizes will vary. Filters larger than 25x30x1 are considered a double filter where there is additional strength down the middle of the filter. It's our policy to list the smallest dimension first. When the filters arrive the label will be displayed as such, this will not impact compatibility - it's just a matter of how you hold the filter. If you have questions or concerns please contact us.
