Frequently Asked Questions
How often should I change filters as part of a fall maintenance kit?
Change air/hood filters every 6–9 months or sooner if visibly dirty. Whole-house and RO cartridges depend on water quality—many manufacturers recommend 6–12 months or specified gallon lifespans; always follow system guidelines and check pressure and taste/clarity for early replacement signs.
What prevents leaks when servicing water housings and RO units?
Use housings with multiple O-rings, inspect and replace O-rings each service, apply food-grade silicone to O-rings if recommended, use proper torque with a supplied wrench, and wrap threaded fittings with Teflon tape. Avoid over-tightening plastic caps which can crack.
Can kitchen range hood filters help furnace efficiency?
Indirectly — keeping kitchen exhaust and hood filters clean reduces grease and particulates that can circulate into return vents. That reduces dust loading on furnace filters and keeps heat exchangers and blower motors cleaner over time.
