What does MERV 16 filter out?

What does MERV 16 filter out?

Aprilaire MERV 16 filters can remove up to 99%* of allergy and asthma triggers, including smoke, pollen, mold, and more. As a bonus, these filters also reduce up to 96%* of virus-sized particles that can make you sick.

What does Arrestance mean?

Arrestance, defined as the ability of a filter to remove synthetic dust, was used to determine the efficiency of low MERV filters. Atmospheric Dust Spot Efficiency, defined as the ability of a filter to remove atmospheric dust from the air, was used for higher MERV filters.

What is the difference between G2 and G3 filter?

G3 relates to the amount of dust retained in the filter and G2 and G3 are the commonly used filter types uses in Aussie air con systems (if you go to a G4 or higher grade of filter this can place additional stress on the fan motor, which isn’t a good thing).

Are MERV 8 filters good enough?

A MERV 8 air filter is efficient at trapping a majority of indoor particulates that could debilitate those with asthma and allergies, or even cause long-term respiratory problems.

What is the MERV scale?

MERV stands for Minimum Efficiency Reporting Value. MERV ratings are on a scale of one to 20 depending on the minimum size of the particles a filter can be expected to capture: A filter with a MERV rating of one to four captures particles greater than 10 micrometers.

What are 30% filters?

For instance, a 30% filter (based on arrestance) means that 30% of the weight of the dust has been captured. Depending on the size of the dust particles the actual number of particles (and hence the percentage of particles) captured may be substantially less.

What is G4 grade filter?

A coarse G4 filter is designed to capture pollen, fog and coarse dust particles (≥10μm). It also captures leaves, insects, textile fibres, sand, ash, mist and hair. 0.4μm and larger particles include mould & plant spores, pet dander, textile dust, skin flakes, yeast cells, insecticide dust and most bacteria.

What is EU filter?

In the European Union, filtration performance is governed by a Standard ‘EU’ rating which categorizes filtration performance by means of the efficiency with which it can trap particles of varying size. This gives approximately 97% efficiency down to 2.5 mm and between 44% (EU6) and 55% (EU7) at 0.1mm.

What’s the difference between MERV 8 and MERV 11?

MERV 8 vs MERV 11 AIR FLOW Fine air particles are 2.5 microns and smaller. At that size, the air particles can get into lung tissue and enter the bloodstream. MERV 11 air filters can filter out a large percentage of fine particles, but a MERV 8 air filter can’t.
