Is An Air Purifier Really Worth It?

With so many new and fancy appliances on the market today, it can be easy to get swept up in the latest crazes – whether it’s a selfie stick or a diffuser for your cat. If you clicked on this article, I’m sure you’ve come across an air purifier and asked yourself a simple question: “is an air purifier really worth it?

This article will answer that question, weighing up the pros and cons of air purifiers and explaining why air purifiers are a good investment for your home.

Air Purifiers

An air purifier is a device that draws in the air in your home and cleans it with a special filter. This filter is designed to remove microscopic and macroscopic dust, which can help you combat mold and fungus while keeping your home cleaner.

Is It Worth?

There are many reasons you may consider investing in an air purifier. In this section, we will briefly explain five of them.

Fewer allergy reactions

If you or any of your family members have allergies, you’ll appreciate what an air cleaner can do to improve the air quality in your home. Air purifiers use a High-Efficiency Particulate Air (HEPA) filter to trap 99.97% of airborne allergens. This includes pollen, dust, mold spores, and pet dander. 

Many people with allergies have reported that they get fewer allergy reactions when using an air purifier. This is because the air in their homes is cleaner, giving them less to react to.

Less dust

Air purifiers are indispensable for anyone living in the city, near a manufacturing plant, or close to a busy road. Every day, your lungs are bombarded with filth – from car exhaust fumes to city smog. This builds up, causing lung infections, allergies, and many diseases. 

While an air purifier can’t fix air pollution, it can reduce the amount of airborne dust in your home. This helps you breathe easier while inside, as well as keeping your furniture and clothing filth-free.


Less bad odor

Air purifiers aren’t just great for allergens and dust: they are excellent in removing bad odor. With an air purifier, you’re not just breathing cleaner air but smelling better air too. Air purifiers can reduce bad odors by using activated carbon filters. Carbon filters are super porous, which makes them effective in absorbing odor.

Less airborne bacteria and viruses

Air purifiers include a high-temperature ceramic core that can kill airborne germs, bacteria, and viruses. While they can’t completely protect you from getting sick, they can reduce the chances that you will catch something from the airborne material in your home. 

If you are particularly concerned with airborne illnesses, choose an air purifier that contains UV-C light. To understand the effects of UV light on bacteria, just watch the following video.

The Cons

Now that we’ve covered the benefits of having an air purifier let’s discuss the negatives. 

First, let’s talk about filters. Most air purifiers use replaceable filters, which need to be replaced every six months. Many people consider this a major inconvenience as it will add to an air purifier’s cost. Depending on the air purifier model you choose, you may have to invest in a filter of a particular shape – which you should take into account when choosing your model. 

While the cost of air purifier filters is annoying, it’s not completely mandatory. If you want to prolong your filter’s life, simply vacuum it once a month or wipe it out with a clean and dry cloth. Easy, peasy!


Second, let’s discuss the cost of the machine. Many air purifiers are very expensive, as they are full of features designed to make the machine easier to use.

These are indispensable to come people but useless to others. While the high cost is annoying, remember that it’s not a “must”. An air purifier with a filter and no other features is still an air purifier, meaning it will give you all the benefits listed above, without the high price tag.


After weighing the major pros and cons, we can say with great certainty that an air purifier is certainly worth it for most people. The pros outweigh the cons by miles (or rather: 4 to 2). Whether you put it on in your home or office, an air purifier will positively impact your overall health. 

So, if you have an allergy, any kind of respiratory problem, or are simply fed up with inhaling dirty and putrid air, you should definitely get an air purifier.
