Affordable HEPA Air Purifiers: Buying Guide
Here are the factors and features you should consider when selecting an inexpensive HEPA air purifier for your home or office:
The first thing you have to be mindful of is the efficiency of a HEPA air purifier. An air purifier that processes the greatest amount of air in the shortest time is the most efficient. You can get an idea of this efficiency from the product description.
In addition, the filter should be able to absorb even the tiniest particles that can be hazardous to your health. So, you need to look for a purifier that filters bacteria, mold, mildew, and dust particles.
Ease of Maintenance
The next important thing you have to be careful about is the ease of maintenance. Some air purifiers require very frequent drainage and filter replacement. This can be both expensive and time-taking.
An air purifier should minimize your worries instead of increasing them. So, you must choose a HEPA air purifier that is easy to maintain and care for.
Another important consideration is the portability of HEPA purifiers. Most HEPA air purifiers work impressively and cover an entire room. But sometimes, you need to take the purifier to other parts of your house.
For this, the air purifier should be lightweight so that it demands less effort to move around.
How Does a HEPA Air Purifier Work?
A HEPA air purifier works on three levels of purification, targeting specific particle sizes.
First off, the large particles that have a thickness of one micron or more are trapped in the mesh of HEPA filters. To provide you a better perspective, human hair has a thickness of 50 microns.
Now, imagine the size of a particle with 50 times less thickness than a single human hair.
Medium-sized particles that have a width between 0.3 and one micron. The HEPA filter mesh traps them as well.
Small-sized particles measuring less than 0.3 micron keep rotating in the mesh fibers due to the zig-zag motion. This way, HEPA air purifiers remove even the tiniest pollutants from the air, making sure you breathe safe and clean air.
Who Should Buy an Affordable HEPA Air Purifier?
HEPA air purifiers are all the rage but they can be expensive. With the increase in the quality and number of features; their price increases as well.
However, not everyone’s budget allows for such expensive purchases. Thus, it is better to go for air purifiers that offer high-quality air purification at low prices.
An affordable HEPA air purifier is best for those who have high humidity levels in their house. Increased humidity leads to mold and mildew growth which can harm your health. So, to stay healthy and active, it is better to go for an affordable air purifier.
What to Look for in an Affordable HEPA Air Purifier?
While looking for a HEPA air purifier, you are bound to come across several models. But, how do you determine the best one for your home?
It’s simple: Just look out for the following:
Area coverage is one of the most important factors when it comes to HEPA air purifiers. You need a purifier that covers your room nicely. If you have a large room, then you need to buy an air purifier that can effectively reach all areas.
However, a smaller air purifier works fine for small rooms or rooms with low humidity levels.
The air purifier has to be able to do what you invest in it for in the first place. If it fails to remove dust and other pollutants from the air, then what is the point of having one? So, effectiveness is a major concern when comparing available options.
Build and Durability
The build and durability of an affordable HEPA air purifier are also vital. The construction should not contradict the interiors of your room since aesthetics and clean air are both important.
The air purifier should be durable so that you do not have to invest in a new purifier every few years.
Filter life is also crucial when buying a HEPA air purifier. Filters actively stop pollutants from passing through them, so there is naturally some wear and tear.
However, the filters should be able to serve you for at least three to four years. Also, you should choose washable filters that you can re-insert in the purifier.
While comparing air purifiers, you need to consider the running cost as well. Sometimes, the running cost can be more expensive than the product itself.
You should buy a HEPA air purifier that does not need frequent filter changes. Similarly, it should have affordable power expenditure to avoid putting a strain on your electricity bills.
HEPA air purifiers offer a range of benefits. But, like all good things, there are a few downsides to them as well such as:

For how long can I use the HEPA Air Purifier?

Do HEPA Air Purifiers limit growth of mold?
HEPA air purifiers help reduce mold growth because they are designed to absorb all impurities from the air. They have proved to be quite effective in mold spore removal. So, you should place a HEPA air purifier in a room with high humidity levels to prevent mold growth.
Is it safe to run the HEPA air purifier when the windows are open?
Yes, you can run the HEPA air purifier with windows open, but it decreases the air purification capability.
