Furnace air filter
1900
The opening that I want to match (after brackets are removed) is 6" by 20" tall by 22" wide
After removing the old filter, I could see the model number I need to replace is Aprilaire 213

Bought a 4-pack of proper filters from Aprilaire. Replaced my impromptu filter. I like the accordion style. They can ship in much smaller boxes. Then just unfold and slide in. And they fold up smaller in the garbage.

| April 2020 | Last of 4 Model 213 filters installed. Need to order more. I'm following the schedule enforced by the Nest thermostat so I'm not recording everything here. |

New house, new filters
Also need to replace the plastic pleats that are all broken:
What's a MERV?

Every time I order filters, my vendor has re-arranged their website. This time they have even dropped the Honeywell filters in favor of a cheaper Magnet brand. I'm still not entirely sure whether we use 16x25x4 or 16x25x5 filters and now I get to figure it out all over again with a new brand and new set of part numbers.
An important detail is that the furnace calls for part number FC100A1029.
51st Ave
Our air filters are 16x25x4 Merv 11 Honeywell FC100A1029 (http://www.airmechanicalinc.com/honeywell_filter_fc100a1029_16x25_2_pack.html)
Follow this link: http://airmechanical.hasyourfilters.com/ And search for our filter part number shows me this product:
Replacement Filter for Honeywell (AM1625) Fits Models F25, F35, F50, F100 F150, F200, F300, 203719 FC100A1029, FC200E1029 F100F1012, F100F2002 Size 16x25x5 (15 3/4x24 3/4x4 3/8)
Ahah! 16x25x5 has an actual depth of 4 3/8". So that is what I want.
A 5-pack of those filters are $31/each with shipping only $9.00. Not bad.
Bah, Air Mechanical switched to a cheaper brand of filter. They are unlabeled and are slightly too big now. And I just bought a batch of 5 of these. I really have to work to wedge them in.
Looking for a local supplier
Ordering through Air Mechanical the filters cost $35 each and shipping is $30. I've got to find a local supplier. It looks like Lowe's is the only hit for a local supplier. https://www.google.com/shopping/product/7316905024457172226?biw=1145&bih=907&q=fc100a1029&bav=on.2,or.r_cp.r_qf.&bvm=bv.81456516,d.cGU&tch=1&ech=1&psi=loCHVJ2xNMq5ogSimoLYBg.1418166423583.18&prds=paur:ClkAsKraX-ecfu0ucFfSimU5RD4QWtrq7u53Dl_SFMVrN4PUeLGVdPuE13ZFYoPfC2TWm_dQxjSLJeoE5BKjlI9bgfMNuzI7pwIbQiNagnYHQIT5NOyzEDzQeRIZAFPVH70N6xGJGsjqQ3TrO35mCNhaB3NWOw,oid:2018564058998831618&lsf=seller:3136905,store:12686908953129303002&ei=9YGHVIv3FcPZoATdm4GQDQ&ved=0CHEQ3QswAA
A comment on the Lowes 16x25x4 filter complains that it is really 4.5 inches thick, which is exactly what I want.
replacement history
| Date | |
|---|---|
| 4/1/2008 | Changed filter after about a year. Used last filter on hand. Bought 2 more filters. |
| 12/18/2008 | Changed filter after the fireplace put a lot of smoke into the system. Took out a MERV 8, put in the first MERV 10. |
| 1/1/2010? | Changed filter after furnace stopped working for renter. |
| ? | Hopefully some changes were unrecorded |
| 3/30/2013 | Completely filthy. Went to Home Depot for replacements. |
| 2/21/2014 | Some dust bunnies, but not clogged. Used last spare, need to buy more. |
| 12/8/2014 | clearly dirty and time to replace. Used 16x25x1 since that is all that I could get from Home Depot. It doesn't fit perfectly and I should probably order the right filters... The 16x25x1 filters were about $20 each. |
| 1/1/2015 | with more dogs and more people in the house, I switched to thinner filters that I replaced more frequently. I went through 3 in 3 months. |
| 4/8/2015 | After the pollen burst in the spring, replaced with longer-lasting 16x25x4 |
| 9/22/2015 | Season is switching from AC to heat. Checked the filter and it looked pretty dirty, so put in a new one. Also vacuumed out the ducts as far as I could reach around the filter. |
| sometime in 2016 | Not all that dirty. Forgot to record the new filter installation. |
| 2/24/2017 | It has been cold enough to keep the furnace going a lot this winter. The filter was pretty grey and fuzzy when changed. |
| 7/15/2017 | After a few days of wildfires in the Gorge, changed the filter and you could see the ash |
| 12/30/2021 | First change after moving back from St Louis. Looks pretty clean, no dog hair. |
| 02/27/2023 | Normal change. Noticeably dirty with fine dust. No dog hair. |
