Nothing destroys the homely feeling of a house like the dust, pet hair, and the smell of last night’s dinner in the air. People have always assumed that air pollution is an issue factories have to deal with, but it is also something families have to face. For decades, companies have boasted of having the best technology for purifying air both in residential and commercial premises. However, most of these technologies do this by producing a small amount of ozone into the air. Unfortunately, ozone has terrible effects on a person’s health. It irritates the lungs among a wide range of adverse reactions. This article reviews some of the best HEPA ozone-free air purifiers and gives you a detailed buyer’s guide of essential features to look for when buying.

Why Ozone-Free Air Purifiers?
As stated earlier, most of the air purifiers in the market produce a small amount of ozone. This has adverse effects, which are worse for people with allergies or those who are asthmatic. Even a ‘safe’ ozone production rate might be dangerous, especially for pets and children, when you run those air purifiers all the time. A recent study found: long term ozone exposure is as harmful as smoking cigarettes a pack daily (read the news).
High-Efficiency Particle Arrestor (HEPA) air purifiers have a fine mesh filter that captures even the smallest airborne particles like pet dander, pollen, tobacco smell, bacteria, and dust mite debris. This mesh is often made of extremely fine glass fiber that can trap all organisms flowing through the air, regardless of how small they are. It is, therefore, highly recommended by asthma and allergy experts. By reducing airborne allergens, they provide a form of relief and help you maintain good health. HEPA air cleaners are entirely safe to use at houses.
Here are some more benefits of HEPA filters:
- Once captured, the particles do not leak back into the air
- It is the most effective way to offer allergy relief
- Small and portable so that it can be moved between rooms
- Its efficiency increases as the filter get dirtier

Factors to consider when choosing the best ozone-free air purifiers: Buyer’s Guide
The size of the filter
Before you go into the market to buy an air purifier, it is recommended that you find out what size you need. The size should be directly proportional to the size of the room. You need an air purifier that can adequately cover the room. There is no one size fits all in these types of gadgets. You, therefore, need to measure your home and buy the right one. In most cases, the average purifier will cover a room between 100 and 400 square feet. If your rooms are larger, you may have to get more than one or get a larger option for maximum coverage. At the same time, you need to think about storage. Do you have enough space to fit the purifier?
Do you need any special features?
You need to think about whether you want the purifier to have any special features like wheels. Digital controls, handles, multiple speed fans, remote controls, programmable timers, filter change indicators, and sensors. These features make it easier for you to operate the device. They give you a higher level of control over their performance. This way, you can save money, conserve energy, and enjoy clean air.
How much maintenance will it need?
The filters need to be changed as often as the manufacturer recommends (the duration varies from one company to another). This will maintain a high level of pollutant removal. As you shop, be sure to factor in the costs of these replacements. Typically, the number of filters you will need through the device’s life are listed on the product specification. These will give you an idea of how expensive or affordable the device’s maintenance will be.
Some HEPA air purifiers are equipped with optional ionizer filter, UV-C sanitizer, or plasma-wave filter, which produces ozone. You can buy these, but remember not to turn them ON to maintain an utterly ozone-free air cleaning.
