Honeywell Home Elite Allergen FPR 10 (1-inch)
Sold by its Home Depot 'FPR 10' rating. The 1-inch version is MERV 13 - but note the same FPR 10 is only MERV 12 in the 4-inch media, which is exactly how a proprietary scale misleads.

Overview
The Honeywell Home Elite Allergen FPR 10 (1-inch) is a 1-inch panel furnace filter rated MERV 13 on the standardized ANSI/ASHRAE 52.2 scale, which captures fine particles including smoke and many bacteria-size particles. It markets a proprietary FPR 10 rating without plainly disclosing the true MERV. Because it is high MERV in a thin 1-inch panel, it also restricts airflow more than the same MERV in deep media - worth checking against your system's static-pressure tolerance. Replaced about 4 times a year, it runs roughly $108 per year.

- - Rating Honesty: 0.0/10

Who it is for
- · Homes targeting smoke, allergens, or fine particles (MERV 13)
Who should skip it
- · Shoppers who want to compare on the real standard - the true MERV is hidden behind a proprietary scale
- · Older or low-static systems - a 1-inch MERV 13 can restrict airflow
How it scored
Verified Filtration
7.0/10 · 30%True ANSI/ASHRAE 52.2 MERV - the only standardized filtration rating. Higher MERV captures finer particles.
- +7MERV 13 or higher AMERV 13 - Captures fine particles including smoke and many bacteria-size particles (MERV 13+).
Total Cost of Ownership
0.0/10 · 25%Computed annual filter cost vs the depth-class median. Cheap 1-inch filters replaced often can cost more than deep media.
- 0Annual filter cost vs class median A$108.00/yr (above class median (expensive to run)) - Computed annual filter cost (price x replacements per year) scored against the depth-class median.
Rating Honesty
0.0/10 · 20%Does the brand print the true MERV, or hide it behind a proprietary MPR/FPR scale? MPR/FPR is not MERV.
- ·Hides true MERV behind a proprietary scale AFPR 10, MERV not disclosed - The proprietary MPR/FPR number is the manufacturer's own scale; the standardized MERV is not plainly shown.
Airflow Fit
0.0/10 · 15%Depth vs MERV. A high-MERV 1-inch filter restricts airflow and can strain the blower; deep media at the same MERV does not.
- ·High MERV in a thin panel BMERV 13 in 1" panel - A high-MERV 1-inch filter has limited surface area and can restrict airflow enough to strain some blowers. Check your system's static-pressure tolerance.
- ·Pressure drop not published Cno initial-resistance figure - The manufacturer publishes no initial-resistance figure; airflow impact is inferred from depth and MERV.
Practical Fit
2.0/10 · 10%Replacement cadence and reusability. Frequent swaps are a maintenance and cost burden.
- +2Frequent replacement B4x per year - Needs replacing every 1-3 months, a recurring cost and chore.
