When it comes to air purification, it's important to consider whether or not investing in a home air purifier is worth it. Before making a decision, it's important to understand the different types of air purifiers and how they work. HEPA filters are one of the most popular types of air purifiers. HEPA stands for High-Efficiency Particulate Air and refers to the fact that these filters allow air to pass through with little resistance while quickly capturing almost all of the particles that the air carries.
Ionizers provide an electrical charge to air particles so that they can be carried to a collection device using an opposite charge. Another type of air purifier is one that works with a disinfectant system. These are designed to kill viruses, bacteria, and fungi. Reusable filters are generally good at removing larger particles from the air, such as dust mites and pollen.
When it comes to the performance of home air purifiers, it's important to consider the size of the room and the type of filter being used. In Auto (similar to medium; the Air does not contain a particle counter to adjust to air conditions, but instead asks you to enter the approximate size of your room, after which the machine chooses a fan speed that Molekule deems appropriate), the air performed worse, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean). In Silent, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). And in Dark plus Auto, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean).
Before investing money in an air purifier, it's important to run an air quality test at home first to see if you need one. The possibility of COVID spreading indoors increases because indoor air circulation and ventilation are not as strong as outdoors. If you decide to go ahead with an air purifier, your first decision is whether you need a portable or whole-house model. Overall, if you need to clean the air in a small space such as a bedroom or office up to approximately 200 square feet, investing in an air purifier is worth it. However, it's important to remember that almost all air purifiers arrive with their filters wrapped and almost all have stickers on the machine or warnings on the leaflet to remove the wrappers.
