I just tried this higher rating filter and found that it is much better than my previous filter. Product performs as described. Found cleaner air and less dust. Very satisfied.
I switched from the lower number control to the 1900 healthy living filrete in the 1 inch version and I do see the difference. My condo is normally very dusty - in general - but it has been a little better. I am on my first 1900 filter.
I have purchased several different micro-particle rating 3M filters and determined that the 1900 is the best all around filter for our needs.
I operate the air conditioning & furnace fan on continuous service (low speed) so our two story house has reduced temperature variations per each floor. Since I operate the ventilation system non-stop, I will usually replace the filter about every 7 to 8 weeks, based on the airflow differential pressure (static) information provided at the thermostat.
I have noticed after using the 1900 series filters that we have less dust particles on surfaces and in the air.
When you visually compare 3M filter products to their competitor filter products you can immediately recognize that the 3M filters are of much higher quality. After using 3M filters for a while, you will notice an improvement in your indoor air quality.
I have used nothing but Filtrete filters since my home was built new 8 years ago. They are a great value and do an excellent job of maintaining clean air inside my home.
I have used Filtrete filters for years now and I love them! I recently found the 1900 Filter and I am so impressed. The filter helps capture so much that even though I have to take medication for my allergies I have reduced symptoms since using these filters like no others.
I had used the regular filters for years but I tried one of these about 6 months ago and the difference in its efficiency in collecting dust is unbelievable!!! I am only dusting every 2 weeks now!!! Love this filter!!!
