BoAir

[wisepole]

I use 1" disposable air filters and change them regularly rated MERV 8. They work okay and are delivered at home. All good but the $$ is slightly bugging me. I looked around and asked around and few suggested Boair 1" 5-Stage Filter. I was wondering if it's worth it since it's lifetime and I intend to wash it out monthly. Location: NJ.
I can not change my duct-work to accommodate anything more than 1" in return. Let's not go down that route, please. I know that 2", 4", 5" are better. Also, I do not have space to install a dedicated media cleaner, HEPA cleaner, etc., etc. I have already done what's necessary to ensure air being pulled is from return only and there are no air gaps, etc.... (did a duct/blower pressure test and everything was satisfactory).
My primary concerns are (a) Protection of the furnace (b) Air flow restrictions (c) House is reasonably protected. I go with disposable or BoAir, it'll take care of (a) and (c). So, effectively my boiling point question: Would BoAir cause MORE air restrictions than the disposables?

MERV 8 is MORE Than adequate.
Use 5" that is fitted for 1" filter housing.

Vacuum a few times. It will last > 10 months.

Claims initial PD of .1" at 1200 CFM, so about the same as any other electrostatic air filter. Has a lifetime warranty, so you have little to lose by trying one.

Electrostatic air filter REQUIRES one to be QUITE DISCIPLINED in performing Regular cleaning.!..!!

DON'T EVEN Start, unless You are that person.

is this going in a grille, or in the ductwork/furnace?
if in the grille, is there room behind the grille for a 4" or 5" filter that fits in the grille?

Ductwork/Furnace. Not grill. Also, I am not considering grill-based at all. In ductwork/furnace: Hardly any space left or right, top or bottom.
Answer ro 2nd. question: I am pretty regular. For the disposables ; I have been very diligent till date!
