How Does The Ultra Allergen Reduction Filter Help Clean The Air In My Home?
When your heat or central air conditioning is on, or if you run your fan continuously, air circulates in your home and passes through your air filter. Filtrete™ filters from 3M contain permanently electrostatically charged fibers that work like tiny magnets to attract and capture the particles in your air. Each of the filters in the Filtrete product line perform differently to meet various needs that people have.  The following table (on packaging) shows types of particles that may be in the air in your home. These particles are measured in microns. Did you know that a human hair is about 70 microns in diameter? Particles smaller than one micro are most important to capture because they make up 99% of the number of particles in your air and can be breathed deep into the lungs.

Microparticle Performance Rating
(Including bacteria, dust, smoke and smog particles)

The above chart (on packaging) is designed to help you compare different filter types. The Performance Rating is a relative measure of a filter's efficiency at capturing airborne particles between 0.3 and 1 micron in size. The higher rating means better filtration efficiency based on independent laboratory tests of leading brands. Note: Particles between 0.3 and 1 micron in size are classified as E1 particles by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE).

Larger Particle Efficiency
(Including pet dander, mold spores, and other fungi)

This graph (on packaging) depicts filter efficiency at capturing particles between 3 and 10 micros in size, which are classified as E3 particles by ASHRAE.

How Often Do I Need To Change My Filter?

Under normal conditions the recommended change interval is three months. However, the effectiveness and life of the filter can vary and will depend on the individual conditions in your home. Unusually dirty duct work, construction work, sanding projects, the number of pets, the presence of smokers, and running the fan continuously are some of the things that can shorten the life of your filter. In these cases, change the filter more frequently.

Do I Have To Worry About Restricted Airflow With Filtrete Filters?

This filter is designed to operate appropriately in most residential furnaces and air conditioning systems. If your Filtrete filter remains in use longer than 3 months, it may begin to restrict airflow or cause the system to malfunction due to its high filtering efficient. It also could restrict airflow in some energy efficient furnace/air conditioning systems. In these cases, change the filter more frequently. If you have any questions, please call us at 1-800-338-3458.

Are Filtrete Filters "Antimicrobial"?

Filtrete filtering material will not support the growth of bacteria, mold, mildew or fungi in normal use. No unnecessary chemicals have been added to this filter.

Is Filter Frame Strength Important?

Yes, it is important for a filter frame to withstand pressure created by air movement through the filter without bending or collapsing. If a frame bends, it can allow unfiltered air to bypass the filter, or if the frame collapses, it can be drawn into the furnace fan. Filtrete filters have reliable frame strength because they were designed to hold up even under severe conditions.

What Is MERV?
Merv 12 at 1.5 meters per second

MERV stands for Minimum Efficiency Reporting Value. It is a number from a test method designed by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). The number is intended to help people compare filters. Generally speaking, a higher MERV indicates better filter performance. This Filtrete filter receives a MERV 12, the highest value obtained by any one-inch residential filter available.

ASHRAE designed MERV to represent, with a single number, a filter's performance over many different particle sizes. However, the MERV calculation for one-inch residential air filters does not consider a filter's ability to capture the particles smaller than one micron in size. 3M believes it is crucial to measure a filter's ability to capture these submicron-sized particles because they can be breathed into the deepest areas of the lungs.

This is why 3M goes beyond MERV with an additional performance rating that focuses on a filter's ability to capture submicron-sized particles. 3M's rating uses the same ASHRAE test method that generates MERV, but uses only the data for capturing particles between 0.3 and 1 micron.

American Lung Association®/ Health House® wants you to know...

  • Many people spend as much as 90% of their time indoors, and indoor levels of many pollutants can be two to five times higher than outdoor levels.
  • The Environmental Protection Agency has identified indoor air pollution as one of the top five urgent environmental risks to public health.
  • Exposure to indoor air pollutants such as smoke, dust, pet dander, molds, and other pollutants can pose health risks and contribute to respiratory disease, allergies, and asthma.

Filtrete filters from 3M are one way to help improve the air quality in your home. You should also control pollutants at their source and adequately ventilate your home as key elements of an overall strategy from improving the quality of air in your home.
