What about that 1" slide rail
filter access?
Why not provide a 2" or 4"
track? More media area usually means better performance
and longer life.

Why not provide an access door on the filter
plenum to prevent chronic by-pass around the filter frame?
An integral filter holding sleeve or channel can be field
designed and installed. Low cost self-adhering neoprene
gaskets work wonders. Duct tape also works.

|
Why not specify a quality commercial/industrial
treated filter media just like the big buildings use?
There are quality filtering materials out there. They are
not expensive and they actually last a lot longer than a
1" filter without significant reduction in airflows.

Up to 95% arrestance efficiency
on what? Smoke? Bacteria? Mould? Lint? Mites? Dander?
All, some or none of the above?
You need to understand the basis for performance claims.

Can you really stop 0.1 micrometer particles
with a passive electrostatic filter or any flat panel filter?
This is the same target particle that needs to be controlled
in Nuclear environments.

How many particles can be found in the unseen
world inside?
Assume that your furnace or air conditioner operated 12
hours per day (more or less) and the flat panel filter sees
1000 cubic feet of air every minute of that time and each
cubic foot of air contains 200,000 particles*,
0.3 microns and larger (that's on a good day).
1000 cubic feet of air X 200,000 particles X 60 minutes
X 12 hours X 365 days = 52,560,000,000,000 particles.
