Types of air purifiers

If you think you are safe from large amounts of air pollutants as soon as you enter a safe environment in your home, think again. Indoor air pollution is a major source of concern. No matter how clean the house is, air pollutants always come in contact with the wind, pets, and people.

Common household air pollutants, such as dust, pet dander, pollen, and mold spores, can cause high levels of allergic reactions and asthma attacks. In extreme cases, these air pollutants can also cause a variety of health problems, including respiratory illness and cancer. Worse still, indoor air pollution can be more damaging than outdoor air pollution because indoor air is much more concentrated than outdoor air. This is very alarming, especially when you spend time indoors with your family.

How does an air purifier work?

An air purifier such as Levoit air purifiers generally consists of one or more filters and a fan that absorbs and circulates the air. As air passes through the filter, contaminants and particles are collected and clean air is pushed into the living room. Filters are generally made of paper, fiber (often fiberglass), or mesh and must be changed regularly to maintain efficiency.

In other words, in addition to the purchase price of the air purifier, it is necessary to consider the cost of operation and the cost of replacing the filter. Operating costs can easily be as high as $ 50 per year, since air purifiers should always be used to benefit. Filter replacements can add up to more than $ 100 a year.

The frequency of filter replacement depends on the type of air purifier and how it is used. Some filters can be reused and washed, but require careful attention and are generally not found in the most effective air purifiers. Reusable filters are generally suitable for removing larger particles from the air, such as mites and pollen. There are also UV filters on the market that claim to destroy biological impurities like fungi and bacteria, but they often require more power and more exposure to be effective.

Other air purifiers use ionizers to attract particles like static negative ions to dust and allergens, causing them to settle out of the air. If you are interested in buying an air purifier that uses an ionizer, make sure there is no ozone, a gas consisting of three oxygen atoms, which is often sold to break down pollutants. Because ozone could be a lung irritant and further aggravate asthma conditions. Usually the air purifiers with ozone will have that listed on packaging or in the marketing descriptions.

The following 5 types are the most popular

HEPA air purifier

HEPA air purifiers are very popular today, but their history dates back to the 1950s. At that time, the US Atomic Energy Commission needed a solution for small radioactive particles. The answer they created was a High Efficiency Particle Arresting (HEPA) Filter. Today, it is used everywhere, from hospitals to beauty salons and homes.

In fact, they’re becoming so popular that many manufacturers now market their devices as “True HEPA” to assure their customers that their products feature legitimate HEPA technology and not some knock-off version.

UV air purifier

You may be familiar with UV lights, but you may not know that it can be used to create a healthier atmosphere in your home. UV cleaners use electromagnetic radiation to kill airborne bacteria and other types of pathogens that can pose a risk. These filters are also a reliable way to solve mold, virus and yeast problems at home.

Unfortunately, this high-tech option doesn’t really stop you from tackling allergens, dust, and solids that may be floating in the air. It also cannot remove air from tobacco smoke, gas, or chemical gases. For this reason, many people use UV air purifiers in combination with other types of filters to ensure full spectrum coverage.

Finally, be sure to spend money buying high quality UV filters. Some of them even produce ozone to do the job, which can be potentially dangerous.

Ionic Air Purifier

Another form of very high-tech air purification is done through an ionic model. These machines are built around an ion generator. Ion generator works by emitting a constant source of negatively charged ions. They attract positively charged allergen particles, dust in the air and other dirt. The exchange between ions and these particles alters the latter until it is too heavy to remain in the air. As a result, they fall to the floor and can be cleaned or vacuumed later, but not sucked.

One of the many reasons why people love ionic air purifiers is that they are very effective in eliminating passive smoking. Despite the many benefits they bring, they are also very affordable. Like UV cleaners, ion versions also produce ozone as a by-product, which is considered dangerous if inhaled. Again, when you buy this type of air purifier, you need to be careful about the brand you are considering.

Carbon filtration Air Purifier

Carbon filters, also known as activated carbon filters, are another category of household appliances that help keep your home clean and healthy. The heart of this filter is activated carbon. It is often in granular form or otherwise produced as a powdered of dust. This material is made so porous that it can have an area of more than 500 m² per gram. Due to the large surface area provided, this filter can absorb large amounts of allergens and contaminants, while taking up little work space.

The process that works with carbon filters is called adsorption. This occurs when organic compounds undergo a chemical reaction with activated carbon and adhere.

Despite the many advantages, this type of air purifier like Winix 5300-2 or Medify ma-50 air purifier is best used in combination with a HEPA unit. When used together, it is highly efficient at trapping and removing lint, dust, mold spores, animal hair, smoke, VOCs, and common household chemicals.
