A pleated device called a high efficiency particulate air (HEPA) filter filters out particles from the air around it. These filters are present in a variety of appliances, including air purifier. We use air purifiers to remove a variety of contaminants and particles from the air in our home.
The Environmental Protection Agency provides some guidance on how to select effective filters, but there is no federal certification or regulation for HEPA filters in the United States. Learn some advice on selecting HEPA filters and how to locate the best air purifier for your house in the following article:
The Purpose Of HEPA air filters
HEPA filters clean the air by removing microscopic fragments of dust, mold, pollen, bacteria, and other contaminants. Companies use a dense, paper-like material that often contains thin glass fibers to make a filter. These glass fibers are present in the form of pleats.

As air particles pass these filters, filters instantly capture pollutants with their fibers. Then, as larger particles adhere to the filter, they block the passage of other smaller particles. HEPA can even capture particles of micron-size. For comparison, a strand of hair ranges in diameter from 17 to 180 microns, and the smallest object the human eye can see is 25 microns.
HEPA filters can remove 99.97% of airborne particles when used in filtration devices like air cleaners and purifiers. Initially, companies used these filters in nuclear power reactors. However, nowadays, numerous new gadgets that can help you purify the air in your house utilize this technology. There are several varieties of these filters which entirely depend on the gadget.
Top four varieties of HEPA filters:
For usage at home, a wide variety of air filters and air purification systems are available. Cleaning tools, air filters, portable air cleaners, whole-home fan systems, heating and cooling equipment, and more can all employ HEPA filters. The objective of these devices is to remove minute particles from the air as it travels through them.
Although they are not the only option, experts say that HEPA filters are quite effective at removing the smallest airborne particles. Additional instances of these filters include:
1. ULPA or ultra-HEPA filters
These have a 99.999 percent capture rate for particles that are 0.3 microns or less.
2. Electrostatic filters
These use a little static charge to attract and hold onto particles as they pass through the filter.
3. Filters using electricity.
These filters have Metal plates or wires to draw the particles having the opposite charge. They are frequently washable and reusable.
4. Filters With Ionization
These filters work by emitting a weak charge that attracts airborne particles like a magnet. This kind of filtering could generate ozone gasses and irritate those who have respiratory conditions.
If you live in a big city, you’re probably breathing in a lot of pollutants, dirt, and dust every day. These pollutants can cause a variety of health problems, especially if you have allergies or asthma. If you want to make sure you’re breathing in clean air, you can buy an air purifier to help clean the air you’re breathing.
How We Choose HEPA Air Purifiers
When it comes to cleansing the air in your home, there are a ton of alternatives, which might be confusing. While the EPA does not endorse any specific brands or models of air filters, it does provide recommendations on how to choose the best option for you. The factors, which formed the basis of our selection procedure, are as follow:
Size Does Matter
Look for portable filters that are suitable for the size of the space you intend to utilize them in. In general, your filter’s clean air delivery rate (CADR) score ought to cover roughly two thirds of the space in the room.
Avoid Ozone-Producing Air Purifiers.
Many air cleaning procedures release the ozone gas as a by-product. Normally, we use Ozone gas to clean and disinfect the air. However, it is also a pollutant that can irritate the lungs and harm them. Typically, people use Ozone air purifiers in their rooms when they are empty. However, you should not use them in small areas when you are there. Moreover, in the USA, purifiers without-ozone generation have received approval from a government agency.

Examine the ratings for the industry.
Although EPA doesn’t set regulations for these filters, HEPA filtration has some set-standards. You need to consider following requirements when buying a filter:
- Specific HEPA filter
- Filter with CADR rating
According to the product’s maker, filters with above-mentioned qualities can capture particles smaller than 1 micron. Purchasing a HEPA filter is a smart way to ensure that the air in your home is clean and healthy. But how do you calculate the filtration of a hepa filter? Let’s take a look at how to get the most out of your filter.
How do you calculate filtration?
Experts evaluate Home air purifiers by using the Clean Air Delivery Rate (CADR). It determines how many cubic feet of air per minute can be filtered. It is also concerned with what size of particles can be eliminated in a given volume of air. Experts use particles of smoke, pollen, and dust for filtration tests. After that, they give a certain rating to each filter. Professionals determine A CADR score based on the amount of these filtered elements in a minute.
Consider the size of the room you wish to filter when determining the CADR rating you require. The more particles the device will remove from the area, and the bigger the room it can service, the higher the CADR rating.
However, experts evaluate Industrial HEPA filters by using minimum efficiency reporting values (MERV) ratings, which range from 1 to 16. CADR is the residential evaluation tool while MERV is the industrial evaluation tool. This system was created by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. Higher values indicate Better filtration power.
To help you understand more about this type of filter, let’s take a closer look at the pricing details of HEPA filters.
Pricing manual Of HEPA filters
The size, capabilities, and effectiveness of an air purifier all affect its pricing. Price ranges from $100 to $10,000 are possible. You can tailor your search by filtration and price range on the majority of e-commerce websites to locate the model that best suits your requirements and price range. HEPA air purifiers are considered the best for removing a broad range of airborne pollutants. But if you’re considering investing in a high-quality air purifier, you should review both the benefits and drawbacks before making a purchase.
Benefits and drawbacks of HEPA air purifiers
Here are the main benefits and drawbacks of HEPA air purifiers. Keep in mind that the size of the space and the device’s filtration capacity should be taken into consideration when picking an air purifier. Additionally, how well the filter works depends on how well you maintain it. A HEPA filter that is soiled or out of date won’t function properly. Check the filter replacement advice provided by the manufacturer. These should typically be changed every 60 to 90 days.
For best results, make sure to abide by the manufacturer’s instructions regarding installation, use, and maintenance. In general, think about why you want an air purifier, how well the gadget filters air, and your spending limit. It all depends on how well a unit will filter the air in the size of the room you will be utilizing it in, even though some units may have an alluring pricing.
If you’re looking for an air purifier to help improve your indoor air quality, we recommend using one with a hepa filter. Not all air purifiers are made equal, so it’s important to do your research before making a purchase. We hope this article has helped give you some information on how to choose the right air purifier for your needs and explained the benefits of using a hepa filter. Thanks for reading!
