There are many types of air purifiers on the market and it may be difficult to decide. So if you want to know how to choose a good air purifier for home use, this text will help. So keep reading and find out more.
There are several important aspects to consider if you not sure hor to choose the right air purifier. They are related to the price, ease of use, functionality, and capacity. So let’s see what these aspects imply.
This implies i) the initial purchase price, and ii) the maintenance price. These two are sometimes related in the sense that there are some expensive models so you initially pay more, but they work without filters or they have washable filters so you do not have any extra costs for filter replacements later.
Typical examples of the types without filters are these BONECO Humidifier Air Washer W300 and Venta LW25 Airwasher 2-in-1 Humidifier and Air Purifier. Both belong to the group of the so-called air washers. The meaning of this term is that air circulates through the machine and all the pollution is deposited in its water tank as if the air is washed.
It is just the opposite with the air purifiers working with HEPA filters. One great example is this enormously popular LEVOIT Air Purifier LV-H132. It is far more affordable but it has filters that you change periodically.
But there are exceptions even in the filterless group, they can be affordable like this Ivation Ozone Generator Air Purifier, Ionizer & Deodorizer, so it depends on how the device works.
Ease of use
This is partly related to the price and the type of the device. If you inspect the items on the market, you might realize that some of those expensive filterless devices are really easy to use, the two mentioned air washers use tap water and there is very little cleaning, they have large tanks, etc.
HEPA purifiers are also easy to use, you simply replace the filter. But this implies costs, so make sure to choose a model that requires less frequent filter replacement. On the other hand, electrostatic filters are great because you can clean them and re-use them, but this means some work for you.
Functionality & types of filters
Air purifiers can be very sophisticated and multifunctional machines and this affects the price. Sometimes you have humidifier, ionizer, purifier in one device, some are with Bluetooth smart design like this Honeywell HPA250B, etc.
• There are several types of filters so choose wisely, some are already mentioned above. The most popular are purifiers with HEPA filters, but you can also have electrostatic air purifiers with washable filters.
• Many of them also have an activated carbon filter in addition to any of the two mentioned previously. This filter is added to remove odors and the simple rule on how to choose is to choose models with more activated carbon and this means heavier. This is particularly important for users who have pets and want to reduce odor.
• Note also that some of these machines have UVC light integrated. You have this in the Honeywell HCM350B Germ-Free Cool Mist Humidifier which is what its name says, a humidifier. But I put it also in the group of purifiers because the water is cleaned by the UVC light, and only completely clean vapor spreads through the room.
• Some purifiers also create negative ions like this SHARP KC860U PlasmaCluster Air Purifier Humidifier. The purpose of this is that ions disperse into the air and they attach to the pollutant and clean the air.
This can imply at least two different things.
• As mentioned above, some of these devices work as air washers, so they have a water tank and the water is used also to humidify the air. So for this type the capacity implies the size of the water tank. In general the bigger tank the better, because you do not have to refill frequently.
• Some models force the room air to circulate through the purifier. Normally this should be done so efficiently that all the air circulates through the device at least 3 times per hour. If you have serious issues with allergens, then go for the models that circulate the air 5 times per hour. As you can imagine, this will also depend on the size of the room. In any case, you will always have this capacity mentioned in the specifications of purifiers.
