3M Filtrete 1500 MPR Ultra Allergen Reduction Filter

Rating: 4 out of 5
  • Currently 4.0/5.0

This is my second time purchasing these filters - I use them on my central heating and air conditioning system. They are superior to lower filtration rated filters based on the particles trapped and air quality. We change the filter every two to three months depending on how much material is trapped.

As clean filters, the product is not restrictive to air flow. Filters will become restrictive if they are not changed when needed. We say filter life is approximately 3 months and this is an approximation. Filter life is actually determined by the user's living conditions and will vary for every user. To determine when the filter needs to be change, we suggest holding it up to the light. When you cannot see light through the filters, it will need to be changed even if it is before 3 months. If you are concerned about airflow, you might want to use the Dust & Pollen filter, which has the lowest pressure drop. The capture rate of this filter is also lower. If you have a high velocity furnace with high fan speed, you may need to change the filters more frequently, every 1 1/2 to 2 months.

The filter has better result than non-ultra allergen reduction ones, according to my nose. However, the filter does not last 3 month as they suggest. We need to check around 2 month, otherwise the filtering effect decreases a lot. These air filters are wonderful! They came custom-packaged in a single dispenser box. They do a great job filtering cat hair, as well as dust. The price is definitely competitive as well. I love my new air filter, and really feel the difference now that it is in my home. I am very impressed with the 3M Filtrete 1500 MPR Ultra Allergen Reduction Filter.
