For a lot of animals in the house, I'd go with a MERV10 4" air cleaner, such as a Honeywell F100. A 20"x20" 4" MERV10 has more surface area than a 20"x20" 2 air filter. Thing is, you probably would need to do some duct modifications to install the cabinet (which holds th filter) in the duct.
For your current 2" MERV13 filter, my only concearn would be if you were using a 1" poly or fiberglass air filter in the past (say a MERV8 or MERV10 rating) and now going to a MERV 13, I'd just check the static pressure of your duct. MERV13 offers more resistance to airflow, and depending on what your static pressure was before going to the MERV13, you could possibly end up hurting your HVAC system over the long haul with a higher MERV rating (higher rate of blower motor burnout over time being the prime victim).
No idea on what a ionizer would do for dogs as I've never followed up with anyone where one was installed, but they do help immensely with other indoor air qality issues. I wouldn't waste my time with a stand alone unit for one room.
I will agree about the price your HVAC guy gave you on the surge protector, but if the sub $600 price was for an install on a iWaveR, REME HELO or Dust Free IAQ ionizer, that's a GREAT price. The reality is a decent duct ionizer costs at least 10 time more than a surge protector.
Thanks for this info. I went with MERV13 because of a chart that showed it catching more stuff then the lower numbers. I never thought about air flow. I'll try a MERV10 the next time I need filters, or do you think I should order then now?
I didn't understand if you think the ionizer works at reducing what is getting on my coils, or if the bigger filter will do the job instead? My thinking is to do a better job of cleaning the coil like you guys are suggesting, and seeing what the 2 inch filter does.
