HomeFilter

Never forget when to replace your HVAC filter. A clogged furnace or air conditioner filter is easy to forget and costly to ignore. HomeFilter tells you exactly when your HVAC filter is due, and reminds you before that day arrives. SET UP IN UNDER A MINUTE Pick your filter size, how often you replace it, and when you last did. HomeFilter shows how many days are left and the date your next filter change is due. A REMINDER BEFORE IT’S DUE Choose to be reminded 7 days, 3 days or 1 day ahead, or on the due date. Your iPhone shows the reminder at 9 AM, with the filter size so you know what to buy. If the change slips, you get a follow-up when it’s overdue. ONE TAP WHEN IT’S DONE Swapped the filter? Tap Mark as changed and the countdown starts again. KNOW YOUR SIZE AT THE STORE Keep the size, brand, model number, notes and a photo with each filter, so you always buy the right one. EVERY HVAC FILTER IN THE HOUSE Upstairs, downstairs, a second system: add each one with its own size and schedule. The filter due next is always at the top. YOUR FRIDGE AND WATER FILTERS TOO The same reminders work for refrigerator water filters, water pitchers, under-sink filters, air purifiers and range hoods. Pick the kind of filter and HomeFilter suggests its usual schedule.
