28X34 MERV 11 This is apparently an odd balll size. Right now I have some in the cart on amazon for $27.42 a pop. Anyone aware of a more economidal source? According to my math, that equates to approx 30 cents a day with a 90 day change interval.

Get some that are half the size on one side and tape 2 together. That's what I do to get a 30'X31" without paying a fortune. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

Always check the actual dimensions of your current filter to ensure a snug fit, as "Exact Fit" versions may differ slightly from "Nominal" versions. < jsuid="Ot4LZc_5r" ="0" -amic="true" -icl-uuid="1b05a6f6-273e-4ed4-ade4-1ed6de36a2af" aria-label="View related s" ="rBl3me" js="click:&Ot4LZc_5p|S9kKve;mouseenter:&Ot4LZc_5p|sbHm2b;mouseleave:&Ot4LZc_5p|Tx5Rb" -wiz-attrbind="=Ot4LZc_5p/C5gNJc;aria-label=Ot4LZc_5p/bOjMyf;=Ot4LZc_5p/UpSNec" -ved="2ahUKEwi92ae8v9iTAxVGpIkEHW3fE-QQye0OegQICRAB" -hveid="CAkQAQ" style="margin: 0px 6px 0px 0px; : rgb233, 235, 240; border-width: initial; border-style: none; border-color: initial; border-radius: 10px; height: 20px; padding: 0px; width: 20px; outline: 0px; cursor: pointer;"> http://www.w3.org/2000/svg" rel="nofollow - http://www.w3.org/2000/svg" viewBox="0 0 24 24"> Would you like to compare bulk discounts for these filters, or are you looking for a washable permanent alternative instead?

i doubt your going to find it cheaper to buy two filters and tape them together... 28 x 34 is a BIG FILTER... not sure why it needs to be that big unless that furnace is HUGE.. our 80,000 BTU furnace uses a 20 x 20 filter..... check the OUTLET size and see if the INLET could be framed smaller... 28 x 20 or 24 x 30 might be more common and might be all you need for square inches ?? You can save a little by going to MERV 8 instead of MERV 11... depending on your needs. ------------- Like them all, but love the "B"s. |

| Might be worth buying a constructed High Efficiency Washable we did on our HP 30x30x2. Keep one throwaway to install as wash out permanent then it dries and goes back in. |
