Air purifiers. They’ve been around for years, but recent events have led to a massive upsurge in their popularity. Even Governor Andrew Cuomo has now made it a rule that malls cannot reopen unless they install air filtration systems that can filter out the coronavirus. As we move through Stage 4 of the recovery, we must continue to take every precaution to ensure the health and safety of both ourselves and others. For homeowners, renters, business owners, and landlords, this might mean investing in an air purifier.
But choosing one of these devices is not as straightforward as you might think. They come in many different models, versions, and sizes that can dramatically affect how efficient they are. To help you navigate this buying process that we’ve written this guide.

What is an Air Purifier?What is an Air Purifier?
As the name suggests, air purifiers clean the air around you. The purification process requires a specialized filtering process that targets microscopic particles that can be damaging to your health. While no brand can claim 100% efficiency, they can still lower the chance that you’ll breathe in harmful particles. Without one, you’ll be relying on nothing but your lungs to filter the air around you. Anyone with strong allergies, asthma, or a respiratory illness can tell you, and this is no fun way to get sick.
Their primary purpose, but even if you don’t suffer from any respiratory illnesses, having an air purifier can still have a dramatic improvement in your health. By removing up to 99% of harmful particles from the air, helps take the pressure and risks off your lungs and allows you to breathe easier. Side benefits of using an air purifier also include more energy, better sleep, and overall better health.
Can Air Purifiers with HEPA filters Protect Against COVID-19?Can Air Purifiers with HEPA filters Protect Against COVID-19?
Air purifiers can combat a wide variety of harmful particles, but the question most people will be asking now is how effective they are against COVID-19? There’s currently a growing body of evidence that small particles containing the virus can hang around in the air for hours. You don’t have to be coughing or doing anything vigorous to exhale these particles. Just inhaling and exhaling the air around you is enough to transmit the virus to someone else in the room. The more enclosed space is, the more danger this poses.
It’s still important to clean surfaces regularly and wear facemasks. But all the indications suggest that having an air purifier can also go a long way towards making indoor spaces safer for everyone. However, these machines come in a wide variety of models and types, some of them wildly exotic and outside the budget of most regular people.
Most experts agree, though, that the best choice for individual buyers and small business owners is a high-efficiency particulate air filtration system or HEPA for short—the most common type of air purifier you’ll see on the commercial market. According to the Environmental protection Agency (EPA), they can remove up to 99.97% of harmful particles that are as small as .3 microns – within the range of the coronavirus.
What else can they Protect Against?What else can they Protect Against?
Apart from COVID-19, air purifiers can also combat a wide variety of other airborne pollutants. Air quality alone makes them a good investment. The most common of these are:
- Plant spore and fungi
- Dust and dust mites
- Pet dander and hair
- Mold spores
- Bacteria and viruses
- Tobacco and wood smoke
- Common household odors
- Toxins from aerosol cans
- Volatile Organic Compounds (VOCs) found in paint, varnish, and cleaning supplies.
Each one of these pollutants can damage a person’s health, regardless of whether they have an allergy to them or not. The only difference is that those with allergies will notice the effects sooner. Eventually, even someone with the most robust health will end up with a health condition after prolonged exposure.
The Air Visual Pro enables you to monitor the air quality within your apartment or home as well as outside. See the video for details.
Do I Need One?Do I Need One?
Anyone who runs a small business should seriously consider investing in an air purifier. The sight alone of one can make a big difference in assuring customers and returning staff that it’s safe to enter. The same applies to property managers and landlords. Of course, we don’t expect you to provide one free-of-charge for all your residents. But having one or two placed in the entrance lobby and staff room can go a long way towards calming nerves and ensuring everyone’s safety. As the year continues, these devices will likely become a ubiquitous sight in residential buildings.
Homeowners and renters also advised considering purchasing one. Along with acting as a shield against COVID-19, they’re just an all-round good investment for protecting against more common airborne pollutants. You’ll also no longer have any issue with common household odors, the air around you will feel much cleaner, and you’ll find you have more energy in the day.

Choosing the Right Type of Air PurifierChoosing the Right Type of Air Purifier
As mentioned, there’s a wide variety of different types of air purifiers to select. The only class that we recommend though is HEPA – the gold standard in air purification. Just know that not every HEPA purifier is as good as another. The only one you should trust is any model that carries the label “True HEPA Filter.” Certified to remove 99.97% of pollutants that are as small as .3 microns. Other types of purifiers are described as “HEPA-like” or “HEPA-type” and aren’t nearly as efficient
How to Choose the Right SizeHow to Choose the Right Size
Size is another significant consideration. Air purifiers aren’t one-size-fits-all machines, so you need to be sure the one you buy is the right size for the room it will be placed in. Buy a small model for use in a large lobby, and you’ll soon find that it doesn’t work nearly as well as you expected. Fortunately, this is easy to avoid, just check the square footage rating of the device and compare it to the room you’ll be placing it in. If the square footage rating is equal to or greater than the intended room size, then the right choice.
Additional Features to ConsiderAdditional Features to Consider
Classic or SmartClassic or Smart
All types of air purifiers come in one of two versions, classic or smart. Classic versions are a traditional design that can’t give you feedback on what sort of impurities it’s removing. You just have to trust that it works. Smart purifiers come with a dedicated mobile app that can give you all sorts of information on how well the device is performing.
This is a common acronym you’ll see on many purifiers, but not all of them. It stands for Air Changes Per Hour, and it tells you how many times the device can recycle the air in a room each hour. For instance, a 4x rating means that the air in a room is being cleaned and recycled four times per hour.
This is another rating that you’ll often see, but not always. It stands for Clean Air Delivery Rate and can be very useful when comparing two or more air purifiers against each other. An air Purifier with this rating means that this device has been independently tested to verify its effectiveness. It does this by assigning a number (anywhere from 10 to 450) to how effective it is at removing the three most common pollutants. These pollutants air dust, tobacco smoke, and pollen, respectively. For example, a CADR rating of 200/220/250 means that this device has a 200 rating for dust, a 220 rating for tobacco smoke, and 250 for pollen. The higher the number, the more effective it is.
Energy ConsumptionEnergy Consumption
Like any electrical device, air purifiers require electricity to operate. Since you’ll have them running consistently, it helps to know how much energy they use before buying. Most use between 5-200 watts of power. You can save on energy costs by purchasing a model with an Energy Star rating.
There’s a host of other features you can consider, but don’t matter much when determining how effective a purifier is. Regardless, these can be nice extras if you think you need them—for instance, a programable timer, filter replacement indicators, digital controls, or automatic air-quality sensors.
Once you have your air purifier set up, be aware that it does require regular maintenance. HEPA purifiers work through the use of a filter that has to be routinely replaced. How often this has to be replaced will be stated on the manufacturer’s guidelines. Filters can range in cost from $15 to $50 and can have a lifespan of anywhere from three months to one year.
Other Ways you Can Improve Air Quality.Other Ways you Can Improve Air Quality.
Getting an air purifier is a considerable step towards improving the air quality of a home or business. However, there are also small steps that you can take to improve things further.
For Homeowners and TenantsFor Homeowners and Tenants
When cooking, turn on a hood vent or open a windowWhen cooking, turn on a hood vent or open a window
Apartments are often tightly packed, allowing for fumes to build up quickly. Cooking can release chemicals, odors, smoke, moisture, and grease that can lead to the build-up of mold and bacteria. You can limit this by using a hood vent when you cook or by opening a window.
Install exhaust fans in your bathroomsInstall exhaust fans in your bathrooms
Bathrooms are a common source of indoor air pollution that can lead to the build-up of mold and mildew. Just like with cooking, you can limit this by installing a fan or opening a window when using the shower or tub.
Limit the use of chemical ingredientsLimit the use of chemical ingredients
When you can, try to stick to non-toxic cleaners. The chemicals found in toxic cleaning products can lead to a host of health problems when allowed to build up. Instead, use all-natural cleaning products.
Minimize dust collectionMinimize dust collection
Carpets, curtains, and other fabrics can act as huge dust magnets. Clean them as regularly as you can to keep dust from building up.
For Landlords and Property ManagersFor Landlords and Property Managers
Regularly test the air quality in your buildingRegularly test the air quality in your building
Even if you’ve got several air purifiers running around the clock in your building, it’s still good policy to have your air quality tested regularly. Have a professional come over and take a sample test of the air.
