Gear Score Methodology
PetPal Gear Score
Reducing Pet Allergies and Dander at Home (2026)
Editorial synthesis of general allergy and veterinary consensus on pet allergens (dander, saliva, and the major cat and dog allergen proteins), the HEPA filtration standard, and MERV filter ratings, combined with manufacturer documentation from Winix, FURminator, Shark, Allerpet, Burt's Bees for Pets, and Filtrete. Product spec claims are drawn from current Amazon product listings. No first-hand product testing and no allergy-symptom testing — PetPalHQ does not run a lab, and only a physician or allergist can address allergy symptoms.
PetPal Gear Score = (Expert Consensus × 0.35) + (Allergen-Reduction Fit × 0.25) + (Safety / Everyday Practicality × 0.20) + (Value × 0.20)Factor breakdown
Expert Consensus
35%Synthesized from general allergy and veterinary consensus on pet allergens, the HEPA filtration standard, MERV filter ratings, and manufacturer documentation. The PetPal Gear Score is a composite of expert opinion and product specification — PetPalHQ does not run a lab, and this score reflects allergen-load reduction at home, never allergy-symptom relief.
Allergen-Reduction Fit
25%How well the item advances one clear layer of the source-to-air system — cutting dander at the source, clearing the settled reservoir, capturing airborne particles, or filtering circulating air — rather than how it performs as a standalone gadget.
Safety / Everyday Practicality
20%Whether the item is safe and gentle for the pet, honest about its limits (over-bathing, filter sizing, HVAC strain), and realistic to use often enough to matter — a control only works if the household actually keeps it up.
Value
20%Cost relative to the layer's contribution, including consumables (filters, shampoo, dander solution) weighed against how much of the household allergen load the item actually removes.
