1. Get the Right Filter

There are three main allergy air purifier technologies that you should be sure to look for before purchasing an air purifier: HEPA filters, Activated Carbon filters, and ionizers. These technologies have been developed to maximize the effectiveness of an air purifier and ensure that your space is free from potential allergy triggers. However, it’s important to note that each of these technologies work in different ways to target specific pollutants, so understanding what each does can help you better solve your individual allergy issues.

HEPA Filters

HEPA (High-Efficiency Particulate Air) filters are designed to capture 99.97% of particles as small as 0.3 microns, making them one of the most effective types of air filters available. These filters work by forcing air through a dense mat of fibers, which captures airborne particles and common allergens including pollen, dust mites, pet dander, mold spores, and fine dust. They can also trap other airborne particles like smoke, bacteria, and some viruses, with some efficiency. Since they remove a significant percentage of allergens from the air, HEPA filters can reduce your exposure to irritants that may trigger your allergies as well as help alleviate symptoms such as sneezing, runny nose, itchy eyes, and other allergic reactions, especially if you suffer from asthma.

Activated Carbon Filters

Activated carbon filters are another option that utilize the power of activated charcoal to enhance air quality. These filters are packed with tiny, highly absorbent pores that trap a wide range of pollutants. When air passes through the filter, contaminants such as volatile organic compounds (VOCs), odors, smoke, and certain gasses are targeted, captured, and retained by the carbon. This process is great at targeting pollutants that traditional filters might miss, providing a more comprehensive cleaning of the air especially when used in conjunction with HEPA filters. If you suffer from allergies, this means relief from those airborne irritants that can exacerbate symptoms.

Ionizers

Lastly, ionizers, also known as ionic filters, work by emitting negatively charged ions into the air. These ions attach themselves to positively charged particles like dust, pollen, smoke, and other allergens, causing them to become heavy and fall to the ground or stick to nearby surfaces, which can then be cleaned up. If you have allergies, ionizers provide relief by reducing the number of allergens in the air, but note that you will still need to clean the surfaces where the pollutants have accumulated. Moreover, some ionizers emit small levels of ozone, which is harmful to our health, which should be a consideration when deciding which air purifier technology you aim to use.

2. Get the Right Size

Choosing the right size air purifier for your space is also an important consideration to make sure it is able to work effectively. To start, calculate the square footage of the room where you’ll use the purifier by measuring the length and width of the room, then multiply these numbers to get the total square footage.

Next, check the Clean Air Delivery Rate (CADR) rating of the air purifier. This is a metric used to measure the effectiveness of an air purifier in removing specific pollutants from the air, including dust, pollen, and smoke. It is expressed in cubic feet per minute (CFM) and indicates how quickly the air purifier can clean the air in a given space. The information on airflow rate and efficiency are also typically provided by the manufacturer. Note that a higher CADR rating means better performance in larger rooms.

Hence, to achieve the best air quality possible, it is important that the ability of the air purifier you select matches the size and needs of the room. You may also want to consider how certain features may best benefit different sized rooms. For instance, if you plan to use it in a living room, a larger unit with a high CADR and advanced smart features, such as real-time air quality monitoring and automatic adjustments, may be best. Alternatively, for a bedroom or office space, you may want to choose a smaller air purifier that operates quietly to minimize disruptions or has a sleep mode to ensure restful nights. At the end of the day, matching the air purifier’s capabilities to your room’s size and specific needs ensures you’ll breathe the cleanest air possible with ease.

3. Check Out Ratings and Certifications

Next, before choosing an air purifier, it is important to look at all of the ratings and certifications. As mentioned, the Clean Air Delivery Rate (CADR) measures the efficiency of the purifier in removing pollutants from the air, with higher numbers indicating better performance. For example, a CADR of 250 is effective for medium-sized rooms, while a CADR of 400 is suitable for larger spaces.

Moreover, the Air Changes per Hour (ACH) measures how many times the total volume of air in a specific space is replaced with fresh or recirculated air each hour. For instance, an ACH of 4 means the air purifier can clean the air in the room four times per hour, which is ideal for bedrooms and offices.

In this chart we show how the size of the room and the CADR can impact how many air changes per hour. Ideally you want 2 air changes per hour. So if you select an air purifier with a CADR of 100, and then you put it in a room that is 4800 cu ft, then you’re not going to get the ACH you need to effectively help your allergies. In this scenario, you’d be wise to go with a larger air purifier that has a higher CADR. In this same example, a CADR of 250 will give you 3 air exchanges in a 4800 cu ft room – this will be effective in cleaning the air and improving allergy symptoms.

It’s important to note that when considering room size, you need to account for the cubic footage, not square footage. This means including the ceiling height in your room measurement. A standard calculation like what we have shown, assumes an 8 foot high ceiling, but as home designs have changed so have ceiling heights. You may have a 10 foot, or even a 14 foot, high ceiling. As the ceiling height goes up, then the ACH will go down.

In addition to the CADR and ACH, there are other important ratings to consider when selecting an air purifier, like the Association of Home Appliance Manufacturers (AHAM) Verifide® seal. This certifies that the air purifier meets stringent standards for performance and safety. It provides extra assurance that the device will improve your indoor air quality.

Lastly, you may want to look for an air purifier with an Energy Star certification, as it means the device is energy-efficient, helping you save on electricity bills while maintaining performance. By checking these ratings and certifications, you can make sure that you are choosing a high-performing and cost-effective air purifier.

4. Think About Extra Features

Now that you have considered the technology, size, and ability of the air purifier, you can take a look at those fun extra or advanced features. For instance, many air purifiers come with a night mode, which is a great option for those who value a peaceful sleep environment. This feature allows the purifier to operate quietly without disturbing your rest, making it perfect for the bedroom. By dimming lights and reducing fan noise, night mode ensures that your air remains allergen-free without compromising your sleep quality.

Another useful feature to keep an eye out for is wireless control. With this capability, you can adjust the settings of your air purifier remotely through your smartphone or a dedicated remote. This is particularly convenient for those moments when you’re out of the house or simply don’t want to get up from the couch. You can easily turn the purifier on or off, change fan speeds, and monitor air quality from anywhere.

In addition, real-time automatic adjustments can be beneficial for maintaining air quality. Some advanced air purifiers are equipped with sensors that detect changes in air quality and adjust their performance accordingly. This means the purifier will ramp up its efforts when it senses more pollutants and scale back when the air is cleaner, ensuring efficient and effective operation at all times.

By considering these advanced features, you can enhance the functionality and convenience of your air purifier, making it an even more valuable addition to your home and saving you from the discomfort of allergies.

5. Look at the Cost

When considering an air purifier, it’s essential to consider the overall cost. The initial cost of the unit can vary widely depending on the brand, features, and size, so maintenance costs are an important factor to assess and typically will include expenses for replacement filters and energy consumption. Additionally, check the warranty offered by the manufacturer. A good warranty can save you money on repairs and provide peace of mind. By considering these factors, you can choose an air purifier that fits your budget and meets your needs.

6. Learn About the Upkeep Needed

Knowing how to maintain your air purifier is key to keeping it running smoothly for the long haul. Regular filter replacements are essential, as clogged filters can reduce performance. Check the manufacturer’s recommendations for how often to replace filters, which can vary from every few months to annually. For example, typical HEPA filters often need replacement every 6 to 12 months, pre-filters may require changing every 3 months, and activated carbon filters generally last between 6 months to a year. However, during peak pollen seasons or if the purifier is placed in a high-allergen area, filters may need to be replaced more frequently to maintain optimal performance and ensure effective allergy relief.

External cleaning is also important to keep your air purifier running smoothly. Dust and wipe down the exterior regularly to prevent build-up. Keeping up with simple maintenance will ensure your air purifier continues to work effectively.
