I have a Lennox PureAir system and need to replace the filter. It came with a MERV 16. The cost is about x. What would happen if I replace the filter with a MERV 10? IWill I notice increased dust in my home. I can get 2 of the MERV 10 for x. The filter size is the same. I don't have kids with allergies.
Thanks for any advice and information.
