There are many different types of filters like COVID-19 filters. They all have different MERV ratings. There are also different types, such as pleated and flat air filters. These types of air filters are designed to be disposable or washable. These filters can remove different types of contaminants, such as the merv 13 filter. Let’s take a look at what to look for in an air filter and how you can choose the right one.

COVID-19 air filter

Russian scientist has developed a new type of COVID-19 filter. According to a new study published in Materials Today Physics this filter can trap 99.8% COVID-19 viruses and kill them in one pass. It is made from commercial nickel foam that has been heated to 200 degrees Celsius. It has been shown to be effective against the anthrax virus. A desk top COVID-19 air filter is also being considered.

MERV ratings

When buying a new filter for your house, it is important to consider the MERV rating. It measures the efficiency of the filter in capturing particulate matter and airborne pollutants. The higher the MERV rating, the better. Filters with a higher rating MERV are more efficient at capturing particles in the air. American Society of Heating, Refrigerating, and Air Conditioning Engineers created the MERV rating scale.

Flat or pleated

To determine if you need a pleated or flat air filter, the first step is to determine the product’s MERV rating. The MERV rating, which is a system that rates air filters based on their efficiency, is what you need to know. A filter that has a higher MERV rating will be more efficient. But be aware that it also means that it gets clogged more easily. The size of the pleated filter is also important. It should not be too big, as it can bend and allow dust particles to pass through.

Disposable or washable

If you’re considering replacing your current furnace air filter, you need to decide between washable and disposable units. Disposable filters are more expensive than washable ones. However, you will need to clean them thoroughly and dry them before reusing them. A spare filter is a good idea to have in case you need to wash it. You will also want a disposable filter with a high minimum efficiency rating (MERV) of 9-12. It should be highly efficient at trapping small particles.

Dust spot efficiency

The amount of particulate material that an air filter can remove from the air stream is what determines its efficiency. This efficiency is determined by the particle size and air flow rate. MERV ratings are measured in percentages, and the highest MERV rating is 16. MERV 13-16 filters have an efficiency rating of 95 percent. They are used in hospitals and commercial buildings. They are measured in percentages.

Most penetrating particle size

Air filters’ efficiency is determined by the size of the most penetrating particles. HEPA filters that are less than 0.3 microns are the most efficient. This is also the standard for most filters. Higher MPPS filters will perform better in other ranges. An average atmospheric air sample contains hundreds of thousands of particles, with some as small as 0.3 microns. This is why it is so important to choose a filter that captures these particles.
