Air Purifiers are amazing at soaking up toxins and tiny dust particles from any room in the house. This makes the air you breath cleaner and safer. While you may not notice the daily benefits of it, your lungs will thank you in the long run. Here are our top picks:
What To Ask Yourself When Buying An Air Purifier
When looking at air purifiers there are a number of important things you should consider. Given that there are so many air purifiers on the market today, there is definitely one for everyone. We advise that you first figure out what you want to optimize for and make your buying decision based off of that. But to help guide you in that quest, here are the things we look for in air purifiers.
How big of a room do you need to purify? This is a very important question to answer. Air purifiers are all measured by how big of a room they can filtrate, measured in square feet. In general, and for the purposes of this buyer’s guide, we can break down rooms into three sizes:
Small: 100 – 200 square feet (home offices and bedrooms)
Medium 200 – 350 square feet (living rooms, large bedrooms)
Large 350 – 500 square feet (open rooms that connect others like a living room/dining room combo)
There are a few things to remember about shopping for the right size air purifier. First, each product will display the maximum square footage they can filter air, at a 99.7% effective rate (more on that later). That measurement assumes an 8 foot ceiling; if you have high ceilings, you will want to do the math on what square foot capacity is right for you. And second, if you have a room that is close to the limit of what an air purifier can cover, you should seriously consider a stronger purifier. This is because anytime the machine picks up on any toxins, dust, odor, etc it will have to work extra hard if it is near its square footage capacity. As a result, it will be loud and make noise for quite a long time. Conversely, a more powerful air purifier will be able to exert less energy, make less noise, and revert back to it’s normal sound level (which is basically undetectable to a normal ear).
In summary, buy a bigger purifier if you have high ceilings or if your room is close to the air purifier’s maximum capacity.
There are three price points you should consider: the initial cost of the machine, the cost of the replacement filters (most require you to change it annually), and the energy cost (let’s just assume it will run 24/7). For the very diligent, looking into the electricity costs can sometimes be a swing vote for one versus another. So be mindful when looking at their energy efficiency ratings and let that guide you in your decision making.
More important than the energy costs however, are the replacement filter costs. Most purifiers suggest replacing filters each year. Some may even say up to eight months! Be sure to factor this in. Pro Tip: Air purifier companies also sell replacement filters to their products. Thus, it is in their best interest to encourage their customers to buy replacement filters as much as possible. We have read plenty of independent reviews and articles that document most air purifiers doing just as well with a one year old filter as a new one. So if you are looking to cut costs, consider replacing your filter every two years instead.
Clean Air Delivery Rate (CADR) and True HEPA Certification
The Clean Air Delivery Rate basically measures how fast an air purifier can produce perfectly clean air. The higher the rate, the faster it will remove unwanted particles and toxins. For example, if a purifier can clean 100 cubic feet of air per minute while removing 90 percent of the air’s particles, it would get a 90 CADR.
High-efficiency particulate air, or HEPA refers to the amount of bad air particles that an air purifier filter will catch. HEPA air filter standards require at least 99.97% of air that passes through to be cleaned. But remember, if you buy an air purifier that claims it has a 99.97% HEPA efficiency rating up to 200 square feet, that rating will go way down if you choose to keep it in a room larger than 200 square feet. Generally speaking, if you see air purifiers that don’t have a True HEPA certification, you shouldn’t buy it.
So Is An Air Purifier Right For Me?
If you value your health and well-being, the answer is an overwhelming yes! I personally swear by them. While I know anecdotal evidence is not scientific fact, I wanted to share my own experience with an air purifier. I have owned my Coway AP-1512HH Mighty Air Purifier for over 18 months now. I bought it mainly because I live in a high pollutant area that also gets a fair amount of smoke when wildfires occur. On smoky days (luckily there have only been a few), my Coway Might Air is able to clean my room within only a few minutes and once it is done, I can’t even hear it anymore. But even more importantly, I find myself no longer going to sleep or waking up with a stuffy nose. Smoke or no smoke, I was constantly having to blow my nose in the morning. Within literally one night of buying my air purifier and sleeping with it on, my nasal passageways had never felt better! And again, I realize this is anecdotal, but I have not gotten sick with any sort of cold like I’m usually prone to. It’s truly been a game changing product for my overall health and well-being. I couldn’t be more happy with it and I would recommend it to everyone!
