Air filter effectiveness against allergens is an important factor to consider when selecting a filter for one's home or business. The two most common types of air filters are FPR and MERV. This raises the question: Are FPR and MERV filters effective against allergens?


To answer this, it must first be established what constitutes a successful defence against airborne particles that cause allergies. Airborne particles such as pollen and dust mites are typically 0.3-10 microns in size, meaning any filter capable of trapping these particles would need to have pores small enough to capture them effectively. Additionally, the durability of the material used will also determine how long the filter can maintain its ability to block airborne pollutants from entering your space.


In terms of performance, FPR filters generally provide good protection against larger allergen particles such as pet dander and mould spores, but may not be able to trap smaller allergen particles like pollen due to their relatively large pore size of 7-8 microns. On the other hand, MERV filters tend to perform better with regards to blocking finer allergen particles given their much smaller pore sizes ranging from 1-4 microns on average. Therefore, while both types of filters may offer some level of protection against allergens, they do vary in terms of overall efficacy depending on their respective specs and type of pollutant being filtered out.


The following list summarises key points about how well each type performs:

* FPR filters provide decent protection against larger allergy causing particles such as pet dander and mould spores; however they cannot trap smaller ones such as pollen

* MERV filters have smaller pores than those found in FPR which allows them to more effectively capture finer allergens

* Both types may offer some level of protection; yet differ in terms of overall efficacy based on specifications

* Durability is also a factor since it affects how long a filter can remain effective at capturing pollutants
