How to choose the best air purifier

You’ve probably heard that you should use the best air purifier at home, but you may be wondering why they’re so important, what they can do for your health and home, and how to choose the best air purifier. Air purifiers aren’t just for people with allergies or asthma—they can improve the quality of air in any household by removing dust and other contaminants like smoke, pollen, and pet dander. Based on my experience with them over the years (and talking with experts), here are a few things that I’d consider if I were buying the best air purifier:

What type of filter do you need?

In the world of air purifiers, there are so many different options. It can be overwhelming to figure out which one is best for you. You should know that it’s important to choose a model with the right filter for your needs. Here’s an overview of some common filters:

Activated carbon filters remove odors and gases from the air, but they don’t trap small particles like pollen or dust.
HEPA filters trap 99% of particles down to 0.3 microns (or 3/1000ths of a millimeter) in size, including mold spores and pet dander. They’re also great at removing smoke from cigarette smoke, so if you live in an area where cigarettes are commonly smoked indoors this might be beneficial for you as well!
Ionizers use electrical charges on both sides of their filter which create negative ions which attract positively charged dust particles like pollen into them before releasing them back into your room when they’re full – so over time, this type may reduce how often you need replacements! However, it also gives off ozone gas which isn’t good for people who have respiratory issues such as asthma so keep that in mind before buying one just because it sounds cool 🙂
Also, note however that ionizers require replacement cartridges every month or two depending on usage levels so keep this fact in mind while shopping around too.

What is your budget?

How much you can afford to spend on the best air purifier depends on your budget, of course.
If you’re concerned about the cost of the unit, don’t be! There are plenty of great models out there that come in at under $300 and offer incredible value for money.
If price is a major consideration for you, I would recommend looking at some of these options first:

How much space do you need to clean?

The size of your rooms, as well as the square footage in each room, will determine how much space you need to clean. The larger the area you want to keep clean, the bigger your air purifier should be. You also need to consider how many people will be using it and what types of particulate matter are unique to that kind of environment. If you have pets or smoke issues, for instance, you’ll want a more powerful model than someone who lives in an apartment with no pets or smoking allowed.

Do you or a family member have allergies?

If you or a family member has allergies, it’s important to consider the following factors when choosing the best air purifier.

What are your allergy triggers? Allergies can be seasonal or year-round. Some common triggers include pollen, dust mites, pet dander, and mold spores. Allergies can cause sneezing, coughing, wheezing and nasal congestion.
Do you have asthma? Best Air purifiers with HEPA filters may help reduce respiratory symptoms caused by asthma flares. If you have severe asthma that requires medication or other treatment beyond the best air purifier (such as an inhaler), talk to your doctor before buying one of these machines yourself.

What will be the noise level?

What will be the noise level? Noise is measured in decibels (dB), and some best air purifiers can get pretty loud. The louder ones are usually more powerful, so if you’re looking for something that cleans well and also has a high-performance rating, look for something around 60 dB or below. If you don’t have to worry about covering up your air purifier with soundproofing foam like I do because it’s right next to your bed, then you may want to go for one that’s even quieter.

For example, our favorite HEPA filter picks on this list (the Sharp Plasmacluster 5-in-1 Air Purifier w/ True HEPA Filter and Sharper Image Ionic Pro Air Purifier with Negative Ion Generator) has a maximum noise output of 57 dB—we found that they were both quiet enough not to wake us up during sleep at night but still worked well enough during the day when we wanted them running full blast in our rooms or office spaces.

However, if these two models are too loud for your needs or taste—and let’s face it: anyone who buys an air purifier probably cares about how much noise their device makes—there are plenty of other options available on Amazon with similar ratings but lower maximum outputs (see our comparison chart).

Do you want additional features like an app or in-home air quality monitoring?

If you want to monitor the air quality in your home, or if you’re interested in setting up a schedule so the purifier runs when you’re at home, look for the best air purifier that has a smart feature.

If you have allergies, it’s also helpful if your air purifier can be programmed to run at certain times of the day. This will ensure that allergens are removed before they get too bad and trigger symptoms when you’re home.

Check the room size range

When determining the size of the best air purifier you should buy, consider how large your room is. If you’re looking to clean a larger space—say, a whole house—you may want to invest in two smaller purifiers instead of one large one. This way, if you ever need to move them one will be easier to transport and set up.

If your room is smaller than average but still large enough for an air purifier (e.g., your bedroom), it may be wise to purchase a single high-powered model that can adequately clean the entire area without being obtrusive or taking up too much space.

Read the Clean Air Delivery Rate (CADR)

The Clean Air Delivery Rate (CADR) is a measurement of how much air a given air purifier can clean in one minute. The higher the CADR number, the more effective an air purifier is at cleaning the air in your home or office.

To find out what type of CADR you need, look at the size of your space and its purpose. If you live in a small apartment with one bedroom, for example, keep in mind that having too big of the best air purifier could mean that it’s not powerful enough—or would be too noisy to function properly. Conversely, if you’re looking for an industrial-strength product that can handle large spaces such as warehouses or offices with multiple rooms, make sure to get something with a high CADR rating so it doesn’t take up too much space unnecessarily.

Choose an air purifier design

Choosing the best air purifier design.

You’ll want to choose the best design for your needs. Best Air purifiers come in different styles and may be better suited for a certain size room or type of home than others. The most common designs are:

Portable air purifiers – Portable models are generally small and light, making them easy to move from room to room as needed. However, they don’t offer the same level of performance as larger units because their filters aren’t as efficient at trapping particles like dust mites and pollen. They often have smaller filters that need to be cleaned more often than those on other models too…

Pick a type of filtration method

The best air purifier is a device that removes pollutants in the air. These pollutants can come from cigarettes, pets, and dust mites. There are many different types of filtration methods that you can choose from when looking for the best air purifier. These include HEPA filters, ionizers, electrostatic filters, activated carbon filters (like charcoal), and microparticle (allergen) filters.

Check the noise level

Noise level is the most important feature to consider when buying the best air purifier. If you can’t sleep with it running, then that’s a big problem! Look for one that’s quiet, especially if you live in an apartment building or have neighbors who will be annoyed by your machine. The best way to find out how loud it will be is by checking out its decibel rating.

You can also look for features like sleep mode or whisper mode so your purifier will run at a lower noise level while it’s functioning.

Choose your smart features

Smart features can help you track the air quality in your home, control your purifier remotely, and even help improve sleep quality. In addition to these benefits, there are several other reasons why it’s important to select a smart device:

Smart air purifiers can provide access to more advanced functions than non-smart models.
They offer more customization options for users of all skill levels.
They’re easier to maintain because of their built-in Wi-Fi connectivity.

Look for maintenance features

Does the filter need to be replaced? Is it washable? Replaceable? Reusable? Recyclable?

You might want to consider purchasing the best air purifier that has replaceable or washable filters that can be cleaned and reused. This will save you money in the long run, as well as help keep your home free of particulates like dust and pollen.

If you have allergies or asthma, you might consider investing in an air purifier to help you breathe better indoors and sleep more soundly at night.

If you have allergies or asthma, you might consider investing in an air purifier to help you breathe better indoors and sleep more soundly at night. You can find a wide range of these products on the market today, from simple plug-in models that cost under $30 to high-end machines that can run up to several hundred dollars.

In general, the most effective air purifiers will be more expensive than those with fewer features; however, it’s also important to look for an air filter that works for your needs and matches your budget. In addition to cost considerations (and other factors like noise levels), here are some things to keep in mind when choosing the best option for your home:

Is safety built into the design? Some models are safer than others because they protect users against allergens such as mold spores and dust mites.
What type of filters should be used? This will depend on what kind of allergens are found in each room where people spend time together—for example: do pets live there? Do kids play there often?

Conclusion

By choosing the best air purifier for your home, you can greatly improve the quality of your indoor air. By making sure that it meets your needs, you’ll get more out of this investment in a healthier lifestyle and less time lost to illness.
