![]() ![]() ![]() You would have to get exact (not list size) measurements from the other filters and compare to the ones that come with the CFB. There are no standards for sizing and different manufacturers have different undercuts from the list size. Q: will this accept 16x16 standard brand name HEPA filters? I do not want to be tied to trying to remember where to get filters every time. If you want a lot of carbon filtration then get a carbon canister filter which has a lot more carbon and a higher contact time for better filtration. It would have to be exactly 16x16 and not undercut. Q: What would be a good way to add carbon filtration to this? Would you recommend a second filter box with the 4 inch carbon impregnated filter, or can I switch the 2 inch MERV 11 prefilter in this box to a 2 inch carbon impregnated filter? Or would one of the carbon canister filters be better?Ī: If you want some carbon filtration then replace the 2 inch MERV 11 with an equivalent size carbon filter. No official maximum but you would get very high pressure drops beyond that. Q: What is the rated airflow capacity of this HEPA filter?Ī: Ideal flow is about 200 cfm or less. The highest test sample we have is 0.464 inches of pressure drop across the filter box at 130 CFM. ![]() Q: What is pressure drop across these 2 filters at 200 cfm?Ī: We have not tested this filter at 200 cfm. You could certainly try to get more with a higher pressure fan such as the Fantech FG 6XL but we have not tested that combo. Q: With the Hepa version of this filter, what would be the appropriate cfm fan to use, to get maximum output of air blowing out? With that fan what would be the maximum cfm of air output?Ī: We typically recommend 200 CFM or less for this hepa unit (Fantech FG 6 fan). At 130 cfm the hepa has a 0.46 inch pressure drop. We do not have fan curves for the RNC unit but most HRVs cannot handle the pressure drop of a HEPA filter. Q: Hi if I were to add this to the intake on my Lifebreath RNC155 HRV at 132Cfm would I need to add an additional fan or will the HRV alone be sufficient?Ī: It would most likely not be sufficient.
