With the Double 11 sales happening recently, I wanted to take advantage of the promotions to buy an air purifier for removing formaldehyde, as my home still had a slight smell after four months of ventilation. Upon researching, I learned that ordinary models are mostly ozone-free but lack disinfection capabilities. Their filters are prone to souring and odor, which can even cause secondary pollution-so I ruled them out immediately.
On the other hand, purifiers with disinfection functions address these issues, but the drawback is that some models release ozone, which poses serious health risks. Since I'm buying an air purifier to improve air quality, it makes no sense to choose one that emits harmful substances. Just as I was about to give up, I finally found an ozone-free model! Here, I'll share tips on avoiding ozone risks-save this if you need it.
1. Check the Type
As mentioned, air purifiers fall into two categories: ordinary models and those with disinfection functions. I've already discussed their pros and cons earlier, so I won't repeat them here.
What I want to emphasize is that while ordinary models are mostly ozone-free, they have unavoidable flaws: firstly, they can't prevent filters from souring or developing odors; secondly, they can't disinfect germs in the air and may even cause secondary pollution-which is quite harmful to health. That's why I personally skipped this type entirely.
2. Look at the Technology
Disinfection-enabled purifiers do solve the problems of ordinary ones, but some disinfection technologies release ozone. According to a relevant study from Fudan University, ozone can worsen respiratory diseases.
But I wasn't ready to give up. With so many disinfection technologies available, surely not all of them carry ozone risks, right? Later, I discovered two reliable options: friction electric air purifiers, which release no ozone while disinfecting germs, and models that release tens of millions of negative ions during operation-both are ozone-free!
3. The Ozone-Free Nàqīng Purifier I Found
If you don't want to delve into the technical details or check certifications, just follow my recommendation! I bought the Nàqīng air purifier, which has been tested and certified by professional institutions. The test report shows an ozone emission level of 0.000-it releases no ozone while improving air quality.
I purchased it last month and have been running it in my bedroom ever since. The smell from the bedside table has already faded significantly. Once the odor from the wardrobe reduces further, I'll move it to the living room to tackle the sofa's smell. Even with the air conditioner running daily during this period, I haven't experienced any discomfort, confirming that it's truly an ozone-free air purifier!
I've shared all this in hopes that everyone can find an ozone-free air purifier that suits their needs!
