How much better is an electrostatic air filter than a 3M Ultra Allergen 1250 filter?
Hello, My house has a 18 year old forced air heating system. It works trouble free since we moved in at 2000. It does not have an electrostatic air filter. I have been using the best 3M filters. The thermostat keeps tracking the hours of use of the filter. When the heater blows air, my nose can feel some kind of discomfort. It is worse when a filter works for 200 hr and more. I am thinking to install an electrostatic air filter, but do not know if it is better enough to get rid of the discomfort. It may need some duct work to put an electrostatic filter. So the first thing I need to find out is how much better an electrostatic air filter is than a 3M Ultra Allergen 1250 filter? Thanks.
No cookie-cutter answer for electrostatic filters
There is no cookie cutter answer for the value of electrostatic filters as each brand has different ratings and can be made of different materials.
My experience is that many electrostatic filters are too restrictive (Dusteater, Allergy Gold) and can be hard to clean our if not properly maintained. The exception to the rule is the BoAir 5-Stage filter. It contains no polyester and has a very low air resistance rating. They cost a little more than your standard permanent filter but my customers love them. I have been using them for over 10 years and have received nothing but good feedback from my customers. I think they are made in Florida.
The bottom line with any filter is balancing air resistance versus dust arrestance.
