Filtrete 20x25x4, AC Furnace Air Filter, MPR 1000 DP, Micro Allergen Defense Deep Pleat, 4-Pack $72 or 2-Pack $36 (exact dimensions 19.88 x 24.63 x 4.2) Amazon S&S

Select S&S to get extra 10% off.
Final price (before tax) for 2-pack = $39.98 * 0.9 = $35.98 (low in stock, but should allow backorders)
Final price for 4-Pack $79.98 * 0.9 = $71.98

I was in the market for 20x25x4 filters and this is by far the best price I could find for MERV-11 filters.

Product description (copied from Amazon link:
The actual filter size is 19 15/16 24 5/8 x 4 3/8 Inches
Outperforms fiberglass, washable and non-electrostatic 3-month pleated 1" home air filters for your furnace, air conditioner, or HVAC system
Exclusive Filtrete Brand 3-in-1 technology from 3M traps unwanted air particles, letting cleaner air flow through
Filtrete 1000 MPR (Microparticle Performance Rating) equates to MERV 11
Good Deal?

Lowe's has this for $37.97 (2 pack) with their version of subscribe & save. You can often find Lowes GC for 10 to 15% off. Not a bad deal, but I wouldn't say its great.

Agree on Lowes being better deal if you put in the work, here is my math on 2 2packs of the Filtrete 20x25x4s:
79.94
-4 for S/S
-8 for promo code (10 off 50 available online for 2 bucks, so net is 8)
-6.8 as i used a gift card i got for 10% off
-5 on the Filtrete Rebate linked above
= 56ish + tax + free shipping

Costco has a better sale imo.

3M 2200 Series Filtrete Filter, 4-pack for $45 limit 5. Many sizes like 14x30x1 which we use.

So my hvac doesn't have a thickness limit. Should I stick with 1" or go thicker?
Does this 4" have a lot more surface area?

Yes, 4" allows for much larger pleats, providing multiple advantages:
  • don't need to change 4" filters nearly as often
  • yet you get better filtering out of them due to lower air velocity through the filter
  • the reduced restriction to airflow allows your HVAC runs more efficiently

If there is, it might be a specialty product not suited to your everyday HVAC system. A HEPA filter will likely introduce too much resistance to your standard HVAC air intakes and could cause major/costly issues.
