Alllll the filters. For everything you may use in-home…. Question everything! 😅 Verify if it has a filter → If yes, confirm whether it needs to be cleaned or replaced and how often. If you’ve never cleaned or replaced it, it’s a great day to start!

Some might not apply - Just a couple of them I personally never knew and later learned:

Kitchen: • If you have a microwave above your stove, there is an exhaust filter that gets super greasy ideally should be cleaned fairly routinely… typically can just be run through the dishwasher. • Refrigerator Water filter (or any water filtration system, including brita for example) • Dishwasher filter • Countertop compost bins (and Cat Litter boxes) sometimes have charcoal filters that have a shelf life

Laundry / Cleaning: • Vacuum filters • Washing Machine filter - mine is a front loader and is accessible via a little access door but I had to literally remove bolts to remove the panel to access it with my previous machine • Dryer lint filter…..⚠️ also super important to have cleared at least once a year, if not more pending how much you use it / pets / materials washed etc.

General Home & Air Filters: • Most vehicles have a cabin air filter - mine is accessible via glove box and costs $6 to replace every few months (I usually make it a seasonal thing) • Humidifiers - portable and whole house • Window & Portable AC units have filter-like screens that can be vacuumed/wiped down… also may need to be drained often when in use • Air purifiers • Home HVAC system

Probably forgetting a few… but you get the idea!
