Air Purifiers 101: Your Complete Air Purifier Guide for 2023 [UPDATED]

Air purifiers have become increasingly popular throughout the United States, as they provide an effective solution for combating air pollution, allergies, and various health issues.

If you're feeling overwhelmed by the numerous air purifier brands on the market, this guide is here to help. We'll answer all your questions and assist you in choosing the perfect air purifier for your home or office.

The benefits of using air purifiers are vast. They are utilized in both residential and commercial settings for a range of purposes, from clearing smoke in commercial areas to alleviating allergy symptoms and maintaining a healthy indoor environment for children.

The main goal of air purifiers is to filter the air, creating a more eco-friendly atmosphere.

What to Look Out for When Purchasing an Air Purifier

Before buying an air purifier for your home or workplace, it's important to consider several factors. Air purifiers come in various types and sizes, with filters that target different airborne contaminants. Think about your specific needs and keep them in mind as you explore your options.

Choosing an Air Purifier: List of Factors to Consider

Air Purifier Size

Similar to air conditioners, air purifiers are available in a range of sizes. It's crucial to think about the coverage area you need before selecting a particular size. If you're looking to purify the air in a bedroom, choose an air purifier with a coverage area that matches your room size. For whole-house air purification, you may need to opt for a larger unit.

The size of your air purifier and its coverage area can affect its efficiency. A smaller unit may not be effective if the space you need to clean is larger than its intended purpose.

Additionally, smaller air purifiers have smaller motors and filters. If you're unsure about the coverage area, consider a unit that covers a larger space — this is ideal for bigger homes and office spaces.

Filtration System

The efficiency of an air purifier depends on its filtration system. There are various types of air filters, each with their unique functions.

HEPA filters (High Efficiency Particulate Air) in air purifiers can address a range of air purification needs, including filtering microns and dust particles.

Activated carbon filters are effective against fumes, smoke, and odors. You'll need to identify your specific needs to select the right filtration system.

Most air purifiers have pre-filters designed to handle larger airborne contaminants. These filters act as additional layers to absorb pollutants before the air reaches the main filter.

If you're unsure about the uses of different filter types, you can seek guidance from air purification companies in your area, such as Airpuria.

MERV Rating

As you explore different air purifiers, you'll come across a feature called MERV Rating. MERV stands for Minimum Efficiency Reporting Values and represents the efficiency and effectiveness of an air filter in capturing particulate matter between 0.3 and 10 microns in size.

The American Society of Heating, Refrigeration, and Air Conditioning Systems (ASHRAE) determines each air purifier's MERV rating using their proprietary testing method. If you're looking to remove specific-sized particles from your home or office, a higher MERV rating is your best option.

For example, combustion particles, organic compounds, and metals are typically smaller than 2.5 microns, while dust, pollen, and mold are usually under 10 microns in size.

The ACH Indicator

Air Change per Hour (ACH) refers to the total number of times the entire volume of air in a room circulates within an hour. A higher air changes per hour number indicates better efficiency for your air purifier.

Some air purifiers have a low ACH rating and may cost less, but they are less effective in tackling smaller air pollutants.

An ACH rating above four is generally considered ideal. 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 is crucial in determining an air purifier's efficiency. It refers to the volume of air that can be purified at the highest speed of the air purifier. Devices with lower CADR take more time to purify the air in a room, so it's important to consider this factor when evaluating your options.

A higher CADR means that an air purifier can clean the air in a room more quickly. Just like ACH, the higher your device's CADR, the better its efficiency will be.

Maintenance Cost

It's essential to think about the maintenance costs of an air purifier before making a purchase. Some air filters are cost-effective and don't require much maintenance. For example, if you're using a HEPA air purifier, you may need to replace the filter every six months.

Washable filters can last up to a year, but you'll need to clean them regularly for efficient performance.

To avoid unexpected expenses, compare the maintenance needs of different units. Some air filters may be expensive upfront but have lower maintenance costs, while others may have a low price tag but require more frequent upkeep.

Noise Level

If you're planning to install an air purifier in your bedroom, it's crucial to choose one with a low noise level so it won't disturb your sleep. Some units may have excellent performance but produce loud fan noises.

To find an air purifier with low noise, look for units with a noise level below 50dB.

Benefits of Using an Air Purifier

By considering these factors, you'll be well on your way to finding the ideal air purifier for your home or office.

Pollen and Dust Allergies

Pollen and dust are common allergens that can cause discomfort for many people. Staying indoors might offer relief for some, but for others, these allergens can still cause irritation.

Besides pollen and dust, there are other airborne contaminants that can trigger allergies.

Air purifiers can help reduce your exposure to these allergens. The filters in these devices are designed to clean the air and minimize allergic reactions.

Indoor Pets

Pets bring joy and companionship to many people's lives. However, they can also contribute to air contamination. While keeping pets clean and vaccinated can help, shedding hair might still cause allergies.

Using an air purifier in your home can ensure that your furry friends don't interfere with the quality of the air you breathe.

Autoimmune Diseases

Individuals with autoimmune diseases need extra care, as exposure to external factors can lead to health complications. Impure air can be particularly harmful to those with these conditions.

Air purifiers can help maintain a cleaner and more sterile indoor environment, reducing health risks for people with autoimmune diseases.

HEPA for the Best Results

For the best results, consider using air purifiers with HEPA 13 or HEPA 14 filters, as they are considered medical-grade and can remove 99.95% to 99.995% of all air particles sized around 0.2 microns.

Essential Places to Use Air Purifiers

Air purifiers can be beneficial in various settings, including homes, offices, and other indoor areas where clean air is crucial.

In addition to the benefits mentioned above, air purifiers can provide relief for those suffering from allergies, improve overall air quality, and create a healthier environment for people with autoimmune diseases.

Evaluate Your Air Quality Needs

By evaluating your specific needs and preferences, you can determine the best air purifier for your situation and enjoy the many advantages it offers.

To Maximize the Benefits from Your Air Purifier

To get the most out of your air purifier, it's essential to place it in the right locations. Some users may experience unsatisfactory results due to improper placement despite having high-quality air purifiers and filters.

Air purifiers need sufficient space and airflow to effectively clean the air. Understanding where to position your air purifier is crucial for achieving and maintaining the desired results.

Place It Near Pollutants

To effectively remove airborne pollutants, place your air purifier close to areas with high concentrations of contaminants.

You can often identify these areas using your senses. For instance, if you have a dust allergy, you might be able to detect the source of the dust. Positioning your air purifier near windows, doors, and vents can be an ideal solution.

If your home has an odor problem, placing the air purifier in areas with strong smells can help eliminate the odor and clean the surrounding air.

If you cannot locate the source of pollutants, consider calling an inspection team to measure and identify airborne contaminants.

Place It 3 to 5 Feet Above the Ground

Air can flow horizontally across a room or vertically from the ceiling. Placing your air purifier at ground level may cause it to miss some horizontally flowing air. Positioning your air purifier a few feet above the ground enables it to clean air coming from both directions.

We recommend placing the unit on a table or a rack, or mounting it on a wall. Consulting your air purification company can help you determine the best spot for your air purifier.

Brands like AlorAir, Austin Air, and FILTR design their air purifiers with wheels, making it easy for you to move the device throughout your home or office and optimize its efficiency with different placements.

Place It in High-Airflow Spots

Air purifiers need high airflow to effectively draw in air. Positioning them near windows and doorways can be beneficial. These spots allow maximum air intake to filter airborne pollutants and allergens.

Placing your air purifier in areas with good airflow helps facilitate the direct flow of air through your filters, eliminating harmful contaminants.

Avoid placing your air purifier in corners, as low airflow may cause it to miss a large portion of the room's air volume.

Place It Away from Humidity

Humid areas can negatively impact your air purifier's performance. Humidity makes the air heavier and more challenging for filters to draw in, forcing air purifiers to work harder and consume more energy.

Damp filters may also have a shorter lifespan, increasing your long-term costs.

Humidity can be particularly harmful to the filters of HEPA air purifiers, which are common in households.

Humidity clogs the filter's surface area, reducing its efficiency and causing poor performance. Kitchens and bathrooms may not be ideal locations for your air purifier.

Potential Negative Effects of Air Purifiers

While air purifiers can significantly improve your home's air quality, certain factors may lead to adverse effects on your indoor environment. Can air purifiers make you sick?

Yes, under specific conditions, your air purifier may affect your health. If you're a first-time air purifier buyer, you should be aware of the potential negative effects of air cleaning units.

Activated Carbon Air Filters

Carbon air filters are highly effective at removing odors, smoke, and various airborne pollutants and chemical fumes. 

However, when cleaning each activated carbon filter, it's essential to wear a mask. Carbon filters work by absorbing harmful pollutants and chemicals, so you want to avoid exposing yourself to the concentrated particles during the cleaning process.

Most users don't mind wearing a mask while cleaning, as they appreciate the long-term effectiveness and benefits of their carbon filters.

Bi-Polar Ionization Units (Ionizers)

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

Some ionizers produce a gas called ozone, which can be harmful when inhaled. If used correctly, ionizers pose no dangers to users.

If you're considering an ionizer, check if the device produces ozone.

If so, use the device only when no one is around to avoid breathing in ozone while still benefiting from clean air in your home or office.

Important Takeaways

- Consider factors like size, filtration system, MERV rating, ACH, CADR, maintenance cost, and noise level when purchasing an air purifier.

- Optimal air purifier placement includes near pollutant sources, 3-5 feet above the ground, in high-airflow spots, and away from humidity.

- Be cautious with activated carbon air filters and bi-polar ionization units (ionizers) as they may have potential negative effects if not used correctly.
