Don't forget to change those furnace filters!
« on: August 13, 2019, 02:19 PM »
Most people on here are probably more proactive and way less lazy than me.

I recently got the motivation to change the furnace filters in the house.  We have 3 of them.  They were definitely past due for a change  [scared].  1 of them was very long past due  [embarassed].  I finally set a reminder on my phone to change the filters every 90 days so hopefully I'll get into a better routine.

I've did the same in Google Calendar for the filter on the air handler (90 Days) , and also the fridge ice maker water filter (6 months). The filter at the sink has an indicator light that flashes when it needs to be changed.

Oh yeah the fridge water filter!  I think the LG filter packaging will tell you it needs to be changed like every 6 months or 200 gallons.  I just wait for the fridge light to come on, which is way more than whatever the filter says.  At least in terms of gallons I believe.

My return air filters get changed every 90 days.  The main air filter (16x25x4) gets changed every 6 months, as do the water and shower filters.  All air filters are the 3M Filtrete type, FPR 10.  Reminders have been in my phone for years.

As I suspected, most FOG users are on top of home maintenance. I'm the real slacker here!

Okay, I’ve gone a few extra months on mine (especially the one in the attic, which involves the inconvenience of dragging a ladder out), but they have never EVER come out looking furrier than my dog!!  What the ???

I converted my 1” filters to 4” filters with a 1” flange. They are rated for 12 months use but because I am in Houston and the A/C runs pretty much constantly I change them every six months. On my birthday and six months later. I write the date on the filters with a sharpie for an added bit of feedback to keep me right. When I originally converted my two returns I had to do a little surgery on some of the insulation board to allow the deeper filter to fit but it was easy and only had to be done once. If you need a picture or a reference number for this type of filter let me know. They are terrific (as long as your plenum/return/filter housing can be easily altered to accept the deeper filters)! These filters are designed to replace 1” filters without having to rebuild the return.

Ya with 2 cats & 2 dogs, changing the filters on a regular basis is a must. We have a thermostat that’s hooked into the internet so we get updates both on the stat and on our phones. Very convenient when you’re in HD and you just happen to get a notification.   [big grin]

We use either 3M or Honeywell Merv 12 filters as they’re the max recommended for home, non-commercial systems.

Changing out filters too early can actually be a detriment as it will not filter out the smaller particles. I put us on a 4 month notification but that’s dependent upon a visual inspection. When it’s time you’ll know it’s time...just ask @GoingMyWay

"just ask @GoingMyWay"

I wonder what the D/P was across those filters.
Reduces efficiency and uses extra electrons.

Ya I hear you Bob.. on the last furnace I installed a Magnehelic and that was wonderful in determining when to change a filter. The downside is that my wife is one of those “close enough” people so that a .2 or a .5 or a .7 reading were all “close enough” for her. That’s when I decided to initiate the internet protocol. It’s so less a strain on relationships.  [big grin]  Now all we have to argue about is the Merv rating. [thumbs up]

The AC gives you an automatic notice when it stops running because the core freezes up.  [tongue]

I'll pass on any electronic system.  If I wanted a system, I'd run a vaccum line up to a gauge on the wall next to the thermostat :) .

So your dogs are trained to change the filters when they get clogged with Cats?

Actually my bet is on the cats. An 8# cat and a 7# cat can run roughshod over a 75# and a 95# retriever.

Not always true.  My Chesapeake Bay retriever would never let my girl friend's cat run "roughshod" over him.  My Chessie would be picking his teeth clean with the cat's claws.

You haven't had AC in 32 years???  How have you survived that long?

I had to look that up - differential pressure!

Yup, I've definitely had that happen a time or 2 before, though I think the 2 most recent times were caused by low refrigerant.
