Air Purifiers 101: Your Complete Air Purifier Guide for 2022

Air purifiers are widely popular all over the U.S. They are the most efficient and effective solution to air pollution problems, allergy problems, and many different health problems! If you’re wondering how to navigate through all of the different air purifier brands available on the market, you may want to read this first. In this guide, we will answer all your questions and help you choose the best air purifier for your home or office. 

There are countless benefits to using air purifiers. Households and workplaces use air purifiers to serve many different purposes. From clearing smoke in commercial zones to alleviating allergy symptoms and maintaining a healthy indoor environment for their kids, the primary purpose of using air purifiers is to filter the air for an environmentally-friendly atmosphere.

What to Look Out for When Purchasing an Air Purifier 

If you want to buy an air purifier for your home or workplace, there are a few factors to consider before making a decision. Air purifiers come in different types and sizes. The filters inside the air purifier unit can cater to several airborne contaminants. Think about why you need an air purifier and have that purpose in mind when filtering through your different options.

Below, you’ll find a list of factors to consider before buying an air purifier. 

Air Purifier Size 

Like air conditioners, air purifiers are available in different sizes. It is essential to consider the coverage area you need before choosing specific size. If you need your air cleansed in a bedroom, be on the lookout for an air purifier that has a coverage area similar to your bedroom. To purify the air throughout an entire house, it may be necessary to opt for a larger unit. 

The size of your air purifier along with its listed coverage area can impact its efficiency. Using a smaller unit may not be effective if the area of air that you need cleaned is larger than its intended purpose. Additionally, smaller air purifier units have smaller motors and filters. If you are unsure about the coverage area, you can opt for a unit that covers maximum space — this is ideal for larger homes and office spaces.

Filtration System 

An air purifier’s efficiency depends on its filtration system. There are different types of air filters for unique purposes. Air purifiers with HEPA filters can cater to multiple air purification needs, including filtering microns and dust particles. Activated carbon filters can serve well against fumes, smoke, and odors. You need to identify your needs to decide on a specific filtration system. 

Many air purifiers have pre-filters designed to handle larger airborne contaminants. They act as additional layers to absorb pollutants before the air reaches the main filter. If you are unfamiliar with the uses of different filter types, you can seek guidance from air purification companies in your area such as Airpuria.

MERV Rating

When sifting through various air cleaners, you may notice a feature known as MERV Rating.

What exactly is MERV Rating?  MERV stands for Minimum Efficiency Reporting Values.  MERVs indicate an air filter’s efficiency and effectiveness for capturing particulate matter that is sized between 0.3 and 10 microns.

Each Air Purifer’s rating is determined by the American Society of Heating, Refrigeration, and Air Conditioning Systems (ASHRAE) using their proprietary testing method.

Higher MERV ratings are your best bet if you’re looking to clean your home or office of particles that are a specific size.  Here are a few examples of particles you may want to remove from your space:

  • Combustion particles, organic compounds, and metals are normally sized below 2.5 microns.
  • Dust, pollen, and mold are normally less than 10 microns.

The ACH Indicator 

Air Change per Hour or ACH refers to the total number of circulations of the total volume of air inside a room within an hour. The better the ACH number, the better the efficiency of your air purifier. Some air purifiers have a low ACH rating. They may cost you less. However, such units fail to tackle smaller air pollutants. 

Opting for an ACH number above four can be your ideal fit. If you want to eliminate dust particles and microscopic allergens, you can rely on ACH 4 air purifiers when making your decision. 

Clean Air Delivery Rate (CADR)

CADR plays a primary role in determining the efficiency of an air-purifying unit. It refers to the volume of air that can be purified at the highest speed of the air purifier. Devices with lower CADR can take more time to purify the air in a room. 

Air purifiers with higher CADR can clean the air in a room faster. Like ACH, the higher your device’s CADR, the better its efficiency will be.

Maintenance Cost

Before you purchase an air purifier, you may need to evaluate its maintenance costs. Some air filters are cost-effective. They do not require extensive maintenance. If you are using HEPA air purifiers, you may need to replace the filter every six months. Washable filters can last up to a year. However, you may need to clean them frequently for efficient performance. 

We recommend comparing the maintenance needs for different units to avoid hefty costs. Some air filters can be expensive to buy but easier to maintain. Others may come with a low-price tag but may have recurring maintenance costs. 

Noise Level 

If you plan to install an air purifier in your bedroom, you’d best choose one that doesn’t keep you up all night! Noise level is one of the primary factors to consider when buying an air purifier. Some units perform well at the expense of loud fan sounds. 

To ensure you choose an air purifier with low noise, search for units with a noise level below 50dB.

Benefits of Using an Air Purifier

Air purifiers can solve more problems than you might have realized. Capable air-cleaning devices can help you maintain a germ-free, pathogen-free, healthy-breathing environment inside your room or office. We believe everyone should make air purification a priority.  To help you understand why, we’ve listed a few of the primary benefits below. 

Breathing Problems 

If you or your family members have bad breathing conditions like asthma, air purifiers might be your knight in shining armor. Breathing problems can result from various factors. Poor air quality is one of the key reasons why people suffer from bad breathing. Regardless of your home’s location, the incoming air may contain some proportion of contaminants harmful to breathing. 

When inhaling, microbes present in the air can reach your lungs and cause breathing complications. If you have a recurring cough or restrained breathing, we suggest opting for an air purifier to resolve your problem. 

Pollen and Dust Allergies 

Pollen and dust are some of the most common causes of allergies. While staying indoors may yield relief for some people, allergens like pollen and dust particles can irritate others. In addition to these common allergens, several other airborne contaminants can cause allergic reactions. 

By using air purifiers, you can eliminate your exposure to these allergen catalysts. The air filters inside your purifying device are designed to decontaminate your air and minimize allergic reactions. 

Indoor Pets

Having pets can be fun.  For many people, nurturing the love of their dog or cat is essential to maintaining a good quality of life. However, having pets almost guarantees exposure to contaminated air. Although vaccinating pets and keeping them clean significantly helps, shedding hair may lead to allergic reactions.

To make sure your indoor pets do not get in the way of breathing clean air, you’ll want to get an air purifier for your house. 

Autoimmune Diseases 

Autoimmune diseases require intensive care. Any exposure to the external environment can lead to health complications. If someone in your family suffers from an autoimmune disease, impure air may be their worst enemy.

Since air purifiers can help you maintain a cleaner, more sterilized indoor environment, those suffering with autoimmune disease will benefit greatly by having one. The filtration process can keep pathogens away, reducing health risks for these individuals.

If you or someone you know has a condition that requires clean air to the highest degree, we highly recommend using air purifiers or air cleaners with HEPA 13 or HEPA 14 filters.

HEPA stands for High-Efficiency Particulate Resistance. In this industry, the term is commonly used in place of air filtration.  HEPA 13 and 14 air filters are the best air filters available.  They are considered medical grade because of their overall efficiency, and their ability to remove 99.95% to 99.995% of all air particles sized around 0.2 microns.  HEPA 13 and HEPA 14 air filters are the best filters on the market for eliminating viruses from your home or office.

Essential Places to Use Air Purifier

To maximize the benefits from your air purifier, we recommend using them in the right places. Many users complain about the poor performance of their air purifiers despite using suitable brands, machines, and filters. Air purification units require ample space and airflow to filter the incoming air. Knowing where to place your air purifier is vital for achieving and maintaining your desired results. 

Place It Near Pollutants 

If you want to get rid of the excessive airborne pollutants, you need to place your air purifier closer to where pollutants are high in concentration. You can identify such areas in your house using your senses. For example, if you have a dust allergy, you may be able to identify where the dust is coming from. Placing your air-cleaning unit near windows, doors, and vents may be an ideal solution. 

If you have an odor problem in the house, you’ll be able to easily identify the high odor concentration areas. Placing your air purifier in these areas can help you eliminate the odor and clean the surrounding air. If you cannot identify the source of pollutants, we recommend calling an inspection team to measure and locate airborne pollutants. 

Place It 3 to 5 Feet Above the Ground 

Air can flow in two primary directions. It can flow horizontally across the room or vertically from the ceiling. If you place your air purifier on a ground level, there’s a chance you may miss out on some of the horizontal-flowing air. If you place your air purifier a few feet above the ground, it can clean air coming from both directions. 

We recommend placing the unit on a table or a rack. One of the ideal locations to mount your air purifying unit is on a wall. By contacting your air purification company, you’ll be able to easily locate the best spot for your air purifier.

Many air purifier brands make their products with placement in mind.  Brands like Aeris Aair, Austin Air, and FLTR create their air purifiers with wheels so the consumer is able to easily move their air cleaning device throughout their home or office.  Moving your air purifier with wheels can be much simpler, making it much easier to optimize the efficiency of your device with different device placements.

Place It in High-Airflow Spots 

An air purifier requires high airflow to pull the air properly. Placing it near windows and doorways can pay off well. These spots allow maximum air intake to filter airborne pollutants and allergens. These airflow choke-points help to facilitate the direct flow of air through your filters to eliminate harmful contaminants. 

By placing your air purifier in the corners of a room, it may miss out on a large portion of air volume due to low airflow. 

Place It Away from Humidity 

Humid areas can affect the performance of your air purifier. Humidity makes the air heavier, which is more difficult for your filters to pull. As a result, air purifiers have to work harder and consume more energy to accomplish their goal. Dampening of air filters can also reduce their lifespan, which increases your costs long term.

Humid air has very adverse effects on HEPA air filters. HEPA filters are the most common among households. Humidity clogs the surface area of the filter, reducing its efficiency and causing a lack of performance. Places like kitchens and bathrooms may not be ideal for your air purifying unit. 

What You Should Avoid with Air Purifiers 

Air purifiers can help you improve your home’s air quality. However, a few factors may cause adverse effects on your indoor environment. Can air purifiers make you sick? The answer is yes. Under specific conditions, your air purifier may affect your health. If it's your first time buying an air purifier, you may need to consider the negative effects of air cleaning units. 

Activated Carbon Air Filters 

Carbon air filters can be highly effective when it comes to odor and smoke removal. You can also use them to get rid of many different airborne pollutants and chemical fumes. 

If you decide to use carbon air filters, we highly recommend wearing a mask while cleaning them. These filters work by absorbing harmful pollutants and chemicals, so you want to avoid exposing yourself to the concentrated absorbed particles during the cleaning process. Most consumers have no qualms about wearing a mask during their cleaning session because they are so happy about the long term effectiveness and benefits of their carbon filters.

Bi-Polar Ionization Units (Ionizers)

Ionizers are common among households and workplaces for air purification. These air purifiers clean their environments by moving the airborne contaminants away from their coverage area.

Some ionizers produce a gas known as ozone. Ozone can be harmful to the body when inhaled. If used correctly, ionizers post no dangers to their users. If you are thinking about getting an ionizer, we recommend checking if the device produces ozone. If that is the case, we recommend only using the device during periods of time when no one is around. This way you can avoid breathing in ozone, while still getting the benefits of clean air in your home or office!


Summing it All Up 

All of the information mentioned above highlights the essential factors you should consider when deciding on your ideal air purifier. Whether you need it for your household or commercial use, it is vital to evaluate each air purifier and corresponding air filter’s purpose.
