The air exchanger is basically the same as opening your windows, except in a more regulated way, plus you get to keep some of the heat. I think they do sell more expensive and better quality units though. If you buy hte venmar units (under 1000$), maybe opening your windows from time to time would do the same job (true!). Your house lets air goes in and out naturally!!īoth Venmar and VanEE sell a range of different units so you should be able to find one suitable. If you have a 30+ year old home, you probably don't need an air exchanger (unless you reinsulated your whole house). They do a good job of getting rid of humidity and changing the house's air. Most units installed in new homes are basic (read cheap) air/heat exchanger. The cost would be around 150-200$ in electricity and heat loss a year. I finally settled for a HEPA filter, it does some exchange but it's like the venmar it does not save energy. But you don't need that in Canada (because we want humidity out most of the times) The best ones (and more expensive) are enthalpy units. if you open it most units have a plastic like cube that stands on its edge. Get either a true HEPA filter unit if you need that. it mixes inside air with cold exterior air, filters it. As for the exchanger is does not recoup heat. Unfortunately, the seals on the unit is very cheap so air goes through, there goes your 99.9% filter. it has a HEPA filter (used in hospitals for preparing IV medications). The 3-in-1 you are talking about is cheap. VanEE is the same company that makes venmar, not sure. Anyone has experience with Venmar air exchanger that HD carries? basically it's a 3-in-1, air exchanger/air purifier/HRV, at the price of ~$900 + installation, it seems a great deal considering other HRVs alone would cost over $1000! Wondering how efficient this Venmar is. Need a feedback quickly as I can apply a 10% on purchase at Home Depot this weekend.
