"We bought a filter system and a set of filter from their Montreal division (aquasanamontreal.com. We tried contacting aquasana.com and aquasanamontreal.com several times for a return or support. for a recent purchase. They did not respond until I placed this review but then my issue was resolved quicklyl. Do not buy from their Montreal Reseller: this is the reason I got no service the first time. Montreal reseller does not respond after sale and aquasana.com will refer you to them for support if you buy from aquasanamontreal.com"
