(1) Based on the 2022 Ipsos US Brand Health Study of Residential HVAC Air Filters. desertcart.com The Filtrete 300 MPR dust reduction filter not only vastly improves the air quality in your home, it also keeps your air conditioning and heating systems running efficiently, saving on utilities and maintenance costs. The electrostatic filter attracts and captures airborne dust, pollen, and other large-particle contaminants to keep surfaces in your home clean and dust-free longer. With each pass through the specially pleated filter, the air in your living space improves, making for a healthier home environment. This high-performance filter outperforms comparable non-electrostatic fiberglass and washable and reusable one-inch filters.Electrostatic Design Captures More ParticlesThe 3M dust reduction filter is made with both positively charged and negatively charged fibers that act like tiny magnets to attract air-polluting contaminants. Since particles in the air are either positively or negatively charged, they are attracted to and captured by the filter and kept out of your living space.Electrostatic filters, including the 3M dust reduction filter, perform better than comparable non-electrostatic fiberglass and washable/reusable filters, because they attract and capture the small, allergy-aggravating microparticles that non-electrostatic filters can't.Improves Indoor Air QualityWith indoor air a surprising two to five times more polluted than outdoor air, the 3M dust reduction filter can make a difference in maintaining a healthier home environment by cleaning air with each pass through the filter.Ideal for capturing large particles from the air, including household dust and pollen, the 3M dust reduction filter features a 300 Microparticle Performance Rating (MPR).Improves EfficiencyThis dust reduction filter also keeps your heating and air conditioning equipment working efficiently by removing dirt and reducing strain on the motor. It is recommended that you change the filter every three months. However, the effectiveness and life of the filter can vary and depend on the individual conditions in your home.About Filtrete Air FiltersFor nearly 25 years, Filtrete filters have delivered cleaner air to millions of homes, becoming a leader in residential air filtration.

## Questions & Answers

**Q: What is the merv rating**
A: Thank you for asking. These filters are a MERV 5.

**Q: Whats the best material to not put strain on the hvac system? also what merv will allow good air quality and not overload or overwork my hvac?**
A: Hello.  I think I understand your question because we had a repair to our central A/C unit this summer and the repair technician suggested to us that the MERV 12 filters that the previous owner had been using were putting too much strain on our system.  He suggested that we come down to these MERV 5 filters, but change them more frequently, which we have done.

**Q: Are these UV resistant?**
A: Thank you for asking. No. If you are having a UV light installed into your system the light should not be able to reach this filter. If you have a UV light already installed and it is near the filter intake, we do not recommend using Filtrete Filters.

**Q: The product description lists 2 sizes- 14x24x1 in large font and 14x14x1 in small font.  Which size will I receive?  What are the actual dimensions?**
A: I received 14x24x1, but they were tough to install
