Three years ago, I found myself asking the same question you might be pondering now: Are air purifiers worth it? After much contemplation, I decided to invest in one. It was a decision that I didn’t make lightly, but one that I certainly don’t regret.
After a few months, it was a revelation to see the actual filth that the HEPA filter had captured. It was a clear, tangible proof of the invisible pollutants that had been lurking in my home. The dust that used to settle around my room is now a thing of the past.
Looking back, my only regret is not having made the investment sooner. The question morphed from “Is it worth it?” to “Why didn’t I do this sooner?” As you read through this article, I hope my personal knowledge and experience can help you make an informed decision about air purifiers.
Air purifiers usually consist of one or more filters and a fan to draw in and circulate air. The fan draws air from the surroundings, passing through the filter to capture pollutants and particles. The purified air is then released back into the living space. The specific steps are here:
The air purifier’s fan pulls in the air from the room, drawing it through the internal filters.
Inside the air purifier, the air passes through a series of filters. Filters are usually made of paper, fiber (usually fiberglass), or mesh. These materials can capture particles of all sizes, including dust, pollen, pet dander, mold spores, and more.
These filters are always HEPA, activated carbon, and pre-filters. Each filter has a specific function:
The air begins its journey, moving through the filters. As it does, contaminants find themselves trapped and swiftly removed. Ultimately, what emerges on the other side is nothing but cleaner, fresher air.
The purified air is then circulated back into the room through the purifier’s output vent.
The air purifier tirelessly does its job. Hour after hour, it repeats its process. With each cycle, it improves indoor air quality. Steadily and continuously, it removes particles and pollutants from the room.
Notes: Regular checks, such as cleaning and replacing filters, can ensure the cleaner’s performance. You should replace the filters usually every 6-12 months.
Air purifiers may be able to filter out some of the following pollutants, but keep in mind that not each device can address all of them:
Air purifiers are worth the money, especially if you face specific problems. You must need it if you are an allergy sufferer, live in an area prone to wildfire smoke or other pollutants, or are a pet owner.
However, air purifiers can be very expensive. The devices we reviewed range in price from $139.99 (Blueair Blue Pure 411 Auto) to $749 (Alen BreatheSmart 75i). If you want to cut back, keep an eye out for specials. (For example, air purifiers may have discounts during sales events like Black Friday.)¬†
There are still consecutive costs. You’ll need to pay for the electricity needed to run these devices, and if run continuously, air purifiers use as much energy as refrigerators.
So, looking for energy-efficient air filters with ratings like Energy Star might be a good idea. Many air purifiers also require you to change the filter regularly (usually every 6 or 12 months), which can cost more than $100.
Also, air filters can catch mold spores, but they can’t do anything about the main reason mold grows: too much wetness. However, dehumidifiers may be better suited to address this issue.
To be short, you have to take a whole consideration. If you are very allergic to pollutants and the awful smell of your pets, the air purifier is an ideal option. And then you will get your fresh room!
After explaining the advantages and drawbacks of it, do you still want to buy one? If you do, there are some tips for you to consider!
Air purifiers can also help reduce the number of dust particles in the air. This may benefit people sensitive to dust or suffer from asthma or other respiratory conditions.
At least 30% of adults in the United States suffer from allergies. Pollen, dust mites, and cat dander are some allergens that air filters can catch. This can help people with allergies feel better.
Smoke can cause various problems for people, including irritation of the eyes, nose, and throat. It can also make asthma and other respiratory conditions worse.
Suppose you have smokers in your home or live in an area prone to wildfires. In that case, air purifiers can help remove cigarette smoke and air pollutants. It can also potentially mitigate the effects of secondhand smoke. They can also help remove smoke from cooking.
Positioning an air purifier optimally is crucial for effectively cleaning the air. Here are 4 general places to place an air purifier:
The best height for an air purifier is typically between 3 to 5 feet off the ground. This allows the air purifier to take advantage of the room’s horizontal and vertical air movements.
Placing your air purifier on top can put it within this ideal height range if you have a sturdy table or surface. This can help maximize its ability to capture and clean the air effectively.
Smaller air purifiers, such as those from Medify Air, Levoit, and Coway, can stay on a desk or tabletop. This ensures they are in the right height range and conveniently accessible.
For the best possible position, consider wall-mounting your air purifier. Wall-mounted air purifiers are typically installed 3 to 5 feet above the ground. This placement takes advantage of the highest airflow in the room, making it an efficient choice for air purification.
If you have a portable air purifier, place it at least a foot away from walls or furniture to allow for even air circulation. Avoid placing air purifiers in corners.
