Air Purifiers Buying Guide – How to Select the Best Air Filters Purifiers for Homes

An air purifier is a great way to keep the air in your home clean. They help eliminate dust, pet dander, pollen, bacteria, and other contaminants that may cause irritation.

If you suffer from allergies, asthma, or respiratory issues, purifiers may help create a safer environment. However, there are many types of purifiers on the market, each with their own pros and cons. If you make the wrong choice, you may not eliminate the pollutants that you want to get rid of.

The following information covers everything you need to know about air purifiers. Discover how these devices work and which features to consider for finding the right option for your home.

How Do Air Purifiers Work?

Most air purifiers use a similar method to help purify the air in a room. They typically include one or more fans and one or more filtration systems placed inside a plastic base. The fan is used to circulate air through the filtration systems and back into the room.

The filtration systems often include individual filters that help trap airborne particles. This may include HEPA filters or activated carbon filters. Other filtration systems include ionizers, ozone emitters, and UV lamps.

After the air passes through the filter it is discharged through a vent and back into the room. The air purifier continuously circulates the air in the room, repeatedly filtering the air and removing more contaminants and possibly odors.

That is the basic function of an air purifier. You can use these devices to help trap dust, pollen, pet dander, and other debris that commonly settles around the house and floats through the air. You may also use a purifier to get rid of cigarette smoke or kill bacteria and viruses.

Eliminating these pollutants may help you breathe better and reduce the risk of respiratory illness or allergic reactions. However, these benefits depend on the quality of the purifier that you choose.

What to Consider When Choosing an Air Purifier

There are a lot of different details to look when selecting an air purifier. The priority of these details may depend on your specific needs and the types of pollutants that you want to keep out of your house. When comparing purifiers, here are the top details to examine:

  • Technology
  • Features
  • Room size
  • Portability
  • Maintenance
  • Noise level

The most important detail to consider is the type of technology used by the purifier. The filtration method impacts the ability of the purifier to remove contaminants from the air. Some filters are more effective than others or only remove certain types of particles from the air.

You should also consider the features that matter most to you. For example, you can find purifiers with remote controls, programmable timers, and additional settings that provide more convenience.

The size of your room may limit the effectiveness of the air purifier. When looking at purifiers, search for a suggested room size or a CFM rating. Typically, you will want 100 CFM per 250 square feet of room space.

The remaining details are mostly related to convenience and your comfort. You may want to pay attention to the portability, maintenance, and noise level of the device.

Different Types of Air Purifiers

As mentioned, the most important consideration is the type of technology and filtration media used to purify your air. The main types of purifying technology include:

  • Ozone purifiers
  • Negative ion purifiers
  • UV technology
  • Activated carbon
  • HEPA filters

These are the main options available. However, some are more effective than others, depending on what you are trying to eliminate. For example, HEPA filters can trap most airborne particles but they do not eliminate odors.

To choose the right type of air purifier technology, you should consider what types of threats you want to eliminate. If you need to remove pollen, pet dander, and other allergens, you will likely need a quality HEPA filter. However, if you are more concerned with odors, you may need a purifier with an activated carbon filter.

There are also air purifiers that use multiple filtration methods to clean your air. Some of the highest-rated purifiers include a washable pre-filter, to help remove contaminants and odors.

Explore the details of each technology. Find out what types of airborne particles they can remove to make the right selection.

Ozone Purifiers

An ozone air purifier works by producing ozone. The purifier breaks oxygen molecules into individual atoms. These atoms attach to other oxygen molecules to create ozone and eliminate airborne pollutants. It is most effective for removing smoke and odors. However, it can also help get rid of mold spores and pollen.

While these purifiers can help clean the air in a room, they are less effective than some of the other technologies. They are also no longer recommended, as the ozone gas that they generate is considered harmful. Ionizers may also produce ozone, which is known to increase the occurrence of asthma symptoms and the risk of various respiratory illnesses.

Negative Ion Purifiers

Negative ion purifiers negatively charge ions which attract airborne particles. When the particle attaches to the ion, it becomes too heavy to stay in the air. Basically, the negative ion purifier weighs down the pollutants, causing them to fall to the ground.

These purifiers do not technically purify the air. They weigh down the molecules. While most of the molecules fall to the ground, they may also land on shelves, electronics, and furniture.

If you choose a negative ion purifier, it is also recommended that you regularly vacuum, sweep, and dust to collect the particles that have fallen from the air. If the particles are not swept up, they can be released back into the air.

UV Technology

UV technology is primarily used to help kill bacteria and viruses. The ultraviolet light is invisible to the human eye. It works by destroying the cells of various microorganisms, either killing them or rendering them inactive.

These air purifiers typically use a fan to draw air into the purifier, where it passes through a pre-filter. The air then passes the UV lamp, which exposes the light to an intense amount of UV radiation.

When you want to kill germs, UV technology is your best option. It can be used in areas where bacteria are more likely to spread, such as the bathroom, kitchen, or anywhere that water is present.

Keep in mind that UV technology does not remove airborne particles. However, this technology is typically paired with other filter systems. The air first passes through one or more filters before reaching the UV lamp.

Activated Carbon

Activated carbon is the most common type of filter used in home air purifiers, water purifiers, and even some air conditioners. The filter is made from a porous texture, providing a surface for air to flow through, while trapping small particles.

Along with trapping dust, pollen, and pet dander, these filters can help trap additional pollutants. Activated carbons are often recommended for helping to eliminate odors, airborne chemicals, smog, tobacco smoke, and ozone.

The activated carbon offers a broad solution for purifying your air, by helping to deal with a wide variety of airborne threats. However, it is not quite as effective as a HEPA filter for trapping certain particles.

HEPA Filters

HEPA filters are the top solution for removing airborne particles. These filters can trap at least 99.97% of all airborne particles measuring more than 0.3 microns. They can trap the main irritants, including dust and dander, along with mold, bacteria, and viruses.

However, if you have a lot of pet dander in your house, then the most effective solution is to use both an air purifier together with the best vacuums for pet hair. That should help you get rid of all the pet dander in your house.

As mentioned, these filters do not remove odors. This is the one limitation of the HEPA filters. If you are concerned about odors, but you want the power of the HEPA filter, look for an air purifier that uses HEPA and activated carbon.

Primary Features of an Air Purifier

While there are many different types of air purifiers using various technologies, they often include many of the same basic features. Here are the main components and options that you should get with most purifiers:

  • Fan
  • Speed settings
  • Programmable Timer
  • Washable filter
  • Servicing indicator light
  • Air quality sensor

Most air purifiers use one or more fans to draw air through the filters. There are purifiers that simply filter the air as it naturally circulates through your home. However, these fan-less purifiers are rarely as effective or efficient.

If the air purifier does have a fan, it may include speed settings. Increasing the speed allows the purifier to clean more air per hour while also creating more noise. With the speed setting, you can set a lower speed for quieter operation when you are sleeping in the same room as the purifier.

You may also find a programmable timer feature on some models. The timer lets you set a specific hour of the day for the purifier to turn on. It may also allow you to set an ending time for the purifier. Instead of running the purifier 24/7, you can set it to turn on just before you arrive home.

Besides the filter or purifying technology, the purifier may include a washable pre-filter. These filters are not always included. However, they help increase the life of the main filter, such as the HEPA or activated carbon filter.

Another useful feature is a servicing indicator light. When the filters require replacement or washing, this light will turn on or flash. This lets you know that the filter is dirty, eliminating the need to regularly check the filter.

An air quality sensor is included on some of the high-end air purifiers. The sensor monitors the air quality in the room and may adjust the speed of the fan based on the readings.

If you want the option to adjust the purifier settings from the comfort of your couch, you may also want to find a purifier that includes a remote control. However, you do not often need to change settings on the purifier, especially with the timer and air quality sensor.

Consider the Size of Your Room

You may also need to consider the size of the room or space where you plan to use the purifier. Unlike air conditioners, air purifiers do not always include a suggested room size. However, they do often list a cubic-feet per minute (CFM) rating.

For the air purifier to be effective, the typical recommendation is that you need 100 CFM of air circulation per 250 square feet of room space. With a 500 square foot room, you may need an air purifier that delivers 200 CFM.

If you do not plan to leave the purifier in the same room throughout the year, you may want a purifier that you can easily move from room to room. Some of the larger purifiers may include caster wheels or carrying handles for easier transport.

Pay Attention to the Noise Level

The next consideration is the maintenance requirements for the purifier. Some purifiers include a washable pre-filter that requires cleaning once per month. You may also need to occasionally clean certain components or replace disposable filters.

The noise level is also an important consideration, especially if you plan to sleep in the same room as the purifier. Some air purifiers may list the decibel level of the purifier when operating at normal speed. The typical decibel rating is 50 decibels, which is about the same level as a normal conversation.

Finding the Right Air Purifier for Your Home

You should now have enough background information to select the best air purifier for your home. To make the right choice, start by considering the types of pollutants that you want to get rid of, which will help you select the best filtration method.

For most homes, a HEPA filter or activated carbon filter should provide the most effective results. However, if you are concerned about bacteria, UV technology may also be beneficial.

You should also think about the types of features that you want. For example, you may want a purifier with caster wheels or handles for easier transport. There are also purifiers with remote controls, digital displays, programmable timers, and even air quality sensors.

Keep these details in mind, along with the size of your room, maintenance requirements, and the noise level of the purifier.

You should also consider taking a few additional steps to reduce the presence of airborne pollutants. Remember to vacuum and dust regularly, especially in areas where pets or children spend a lot of time. Keeping your home clean can help limit dust and debris, reducing the demand on your purifier.
