Buying Guide for Best Small Air Purifier in 2021
Buying a small air purifier is a genuinely hectic job because it involves a lot of market research and many other things. However, in our detailed buying guide, we will describe the top most important things you should look for in a small air purifier before making any final decision.
We all know that air purifiers come with a wide range of options and features, so it becomes pretty hard to stick to any specific model in a competitive marketplace. So instead, we will highlight few main buying factors below that will make your decision-making process smooth and more straightforward.
The pre-filter technology is an essential feature that you should always look for while buying a small air purifier. It helps to capture the largest particles of dust, pet dander, and other air-borne contaminants. In addition, due to these pre-filters, the pressure or strain on the small internal filters is significantly reduced that further helps to extend the lifespan of an air purifier. So remember, if you plan to buy a small air purifier for your room or office, you must look for this specific feature.
There isn’t any direct relation between the efficiency of an air purifier and digital controls, and still a worthy buying factor to consider for many reasons. With these digital controls, the users can easily control the air quality as per their requirements without any hassles.
Filter Replacement Indicator
The filter replacement indicator is another most critical buying factor that you should never ignore while looking for an air purifier. Whenever the filter replacement indicator is turned on, you will have to change the filters because the filters will be clogged with air-borne pollutants once the indicator is turned on.
Programmable Timers are very crucial for small air purifiers due to many reasons. Moreover, small air purifiers are also slightly more sensitive, especially when they are kept on for long durations without any break. A programmable timer option will enable you to select the specific time intervals in which the air purifier will be automatically turned off. Thus, it will not only increase the lifespan of your air purifier but will also help you to save energy.
The carrying handle makes the portability of an air purifier very convenient and easy. You must consider those particular models that are equipped with a carrying handle option so that you can transport it easily from one place to another without any hassles.
Air Quality Sensors
The air quality sensor helps to determine the air quality for some particular pollutants, especially while the air purifier is running. This specific option will automatically adjust the air quality in a matter of few seconds.
If you are thinking of buying a reliable air purifier that you can use for an extended period, you must consider those specific models that offer an extended warranty. The extended warranty period will help you to secure your investment, especially if you are trying any new manufacturer or brand for the first time.
Finally, considering your room size before purchasing a small air purifier is a critical buying factor that you should never ignore. Small air purifiers are suitable for most small-sized rooms but still necessary to compare your room size with the working efficiency of an air purifier mentioned in the user manual.
