Laura is a doctor of air purification and a house mother. Because she suffers from rhinitis, she took the initiative to find our website, hoping to test and review air purifiers. She has always hoped to find a purifier that can promote air circulation.
We tested 24 different air purifiers. We show you our ranking of the Three best air purifiers at the bottom of this post, based on our expert opinions and consumer reviews.
Do you often suffer from repeated attacks of influenza arinitis in autumn and winter due to cold and heat that stimulate the spread of viruses? Are you annoyed by fluff flying around your home and the smell of pets?
If you believe that the quality of the air around you is very important, you will be interested in this article.
In the past 20 years, with the development of society, viruses, bacteria, house dust mites, pets and other allergens have caused us to be almost constantly affected by the bad air environment, but there are various problems in the body without knowing it.. ..
Therefore, people pay more and more attention to air purifiers.
Most people are pleasantly surprised when they invest in a quality air purifier. Because it can improve the air environment for the whole family, remove all kinds of bacteria in the air, prevent people from inhaling them, and make the home life of parents and children better.
When I advise someone to buy a high quality air purifier, I am often asked:
“But is it really worth it?”
………
If I wanted to make more money for myself, I wouldn’t take it up in the first place. I don’t need to spend years researching air purification.
You Should Look For Air Purifiers with :
Purification Index
Some purifiers have poor projection and low cleaning efficiency，In our testing, we found that they remove gases and odors with HEPA to capture 99.97% of particles with a size of 0.3 microns.
A good air purifier can filter H1NI and other common viruses at least up to 99.9%, this is the best measure.
Intelligent temperature monitoring
If you want a clean air quality environment, look for a model with air quality monitoring. Usually, this is an advantage that only the hollow air purifiers have, as it is difficult to implement in the design of a regular air purifier.
Negative ion technology to combat pollution
I think you often hear the term negative ions because it can release millions of negative ions to actively clean dust, bacteria and smoke. It is especially important to create a habitat that cares for mothers and babies. In our tests, this is certainly the case. Cleaners with negative ions are more effective and pure in taming impurities.
Timing function
The air purification time can be adjusted according to the personal home situation, and the intelligent remote control is very practical. It can flexibly control the wind speed or turn the machine on and off periodically while you sleep.
You Should Avoid Air Purifiers with :
Heavy and bulky models
The volume is too large, it is inconvenient to move to other places, and it takes up space
Noisy models
The sound is too loud and affects daily life. Most air purifiers manufactured before 2016 have a sound level between 40-80db, which in the worst case corresponds to a plane taking off. Now a good air purifier is lower than 35DB.
Due to advances in motor technology, some newer models are almost half as loud, meaning you can actually avoid waking up the whole house when using air purifiers
Lack of additional functionality
In addition to the cleaning function, many cleaners now also have cooling and heating functions, which greatly reduces the need to purchase a number of household appliances.
Of course, this is also a feature that only hollow air purifiers have, as the airflow generated by the hollow technology can be used to adjust temperature sensing
Beyond the budget price
We are committed to seeking cost-effective products and try to use a lower price while enjoying a high-quality life. Of course, if you are rich, you can ignore this suggestion.
We evaluated Air Purifiers based on 7 criteria
- Filtering function
- Air quality test
- Air freshness
- Timing function
- Value for money
- Noise
- Appearance and volume

- Filter passive smoking and cat urine odors up to 97%
- Hollow air intake
- Best value for money
- Strongest airflow
- Fastest air purification speed (6 min/10 square meters)
- Fastest removal of formaldehyde 0.1s
- Intelligent temperature control
- Lowest sound level in test (below 35db)
- Over 10 million negative ions emitted
- Different heat and wind speed settings
- 2 sizes for option (18 inch and 46 inch)
- Timing setting for remote control
- Supplement with cold air/hot air function, year-round use.
Review
In our practical test, we asked randomly selected testers about their user experience. The air purifier fan proved to be a clear favorite with their luxurious looks and useful 3 in 1 function(heater , cooler , air pure). It has reached the ultimate purification function, can filter 99.9% of common viruses such as H1N1 and remove various odors, improving air quality to the greatest extent possible.
Features: The powerful airflow can also clean the entire room with maximum range, and the quiet operation does not affect the air supply effect.
At the same time, it also has a three-in-one function, hot air, cold air, and air purification. Thanks to the hollow reality, we will not be injured by the hot wire of the hot air
Hollow Design: The hollow design makes this purifier not only clean, but also has the effect of hot air and cold air, which can clean all year round and can be used as a cooling and heating fan. The price is relatively reasonable and the three-in-one function meets daily needs.
Two Size :Another feature of this air purifier fan is that it comes in two sizes. The 18-inch machine is their best-selling machine. I think after using the vacuum cleaner, the 18-inch machine is more suitable for home use. It is relatively light and suitable for moving. Of course, a 46-inch machine is a better choice for large rooms. The 46-inch filtering capacity will be more powerful
Service Commitment: The manufacturer is obviously very confident in its product. That’s why he openly promotes his money-back guarantee. And customer service kept in touch with me throughout the entire purchase and tried their best to answer all my questions, thank you Ben.
Defect: Sometimes they sell too fast and there may be a sell-out situation.

Review
It should come as no surprise that the Dyson HP 09 is one of the models I get the most questions about.
This purifier has received a lot of attention since its groundbreaking technology was introduced in 2016.
As mentioned earlier in this article, the purification, cooling and heating functions are all complete, the airflow is good and the appearance is beautiful, but there are still some shortcomings.
For example, in our tests we found that its sound is too loud, which affects sleep, and its weight is also bulky.
Note here, I’m not saying this purifier is bad, I think the Dyson HP09 is probably one of the best air purifiers you can buy, but if you compare it to other purifiers, it’s expensive Very expensive, to same price as you can buy many household appliances with good individual functions.
For families with limited budget, it is not the best choice in terms of cost performance.

Pros
- The filter screen can remove nanoscale particles down to 0.003 microns in size
- 8 minutes of ultra-fast cleaning
Cons
- No UV and ozone sterilization function
- It takes a bitter taste after a while
- Complicated installation
Review
Has many models of air purifiers similar to the above traditional air purifiers and there is no distinct difference. So we picked one of their newer models for comparison.
The cleaning function is basically in line with the needs of the general public, and the cleaning speed is also good. The filter is said to be able to remove nanoscale particles as small as 0.003 microns.
But we also found many obvious flaws in the test, such as B. Loud noise, the device smells strange after a while and so on.
Simple function, only cleaning function.
