All the products mentioned in this question are excellent products with peak performance. There are only 6 technologies available to you for whole house sub-micron particles control and you have mentioned 3 of them. Remember that 98% of all particles that you breathe measure below one micron in size and “filters” don’t have small enough holes to collect particles this small. If they did they would restrict air flow more than they do now. Air Cleaners allow for proper air flow while using magnetic attraction technology to stop and permanently capture these particles. The Elevated Air Polarized Media Air Cleaner has equivalent efficiency ratings as those mentioned and because of its unique compact design it can be installed and maintained at half the price.
