5 Key Things To Consider Before Buying An Air Purifier

We strongly believe that the needs of different customers may vary depending on their location, type of interior work inside the house, surroundings and so on. Now that we have reviewed all top products on our list, here are a few things that will help you pick the most suitable and best air purifier for VOCs and Formaldehyde.

1. Deciding the right size

One of the most important points to consider is the size of an air purifier and this directly depends on the area that you wish to cover and cleanse. To determine the right size, we suggest that you consider the square footage area of the room that you wish to purify. This can be calculated by measuring the length and width of the area and multiplying them.

Again, if you have respiratory issues, asthma, or allergies, you may want to look for a product that helps in managing your symptoms. We suggest that you consider an air purifier that changes air per hour.  ACH value indicates the number of times a device purifies air within an hour. The standard sizes include small, medium, large, and the whole house.

2. Type of filter

The quality of filter used in an air purifier determines its effectiveness and specific filters are used for targeting the different components of air. The most common type is the HEPA or High-Efficiency Particulate Air filter which is capable of eliminating up to 99.9% airborne particles of up to 0.3-micron size.

Some models come with additional filters capable of trapping ultrafine particles that are invisible to the eye and finer than 0.3 microns. Please note that HEPA filters cannot remove odor. If you are concerned about bad odor, choose a device that includes activated carbon filter along with true HEPA filter. We also suggest that you choose a product that includes pre-filter to extend the lifespan of a product.

3. Special Features

Besides the type of filter used in the air purifier, there are several other features that increase the user-friendliness of a device and make it more useful. Some of the additional features you may want to include are caster wheels for easy mobility, digital controls, multiple fan speeds, filter change indicators, handles, air quality sensors, remote controls, and many more.

If you look at the higher-end segment, you will also find models that come with smart features such as connectivity with a mobile phone, wi-fi and so on. To reduce electricity consumption and save money, we recommend buying air purifiers that are Energy Star-rated.

4. Where to keep the air purifier

Most people prefer keeping the air purifier in the bedroom or living area as this is where the family spends most of the time. Even if you buy a portable device, it can purify only one room at a time, so you may want/ need to buy multiple devices to meet your needs. Alternatively, you may choose to buy a device with caster wheels or handle to move it from one room to another with ease.

Another popular option these days is the whole house air purifier. These devices are typically connected with the HVAC systems to purify the indoor air while it cools, heats, or ventilates the house.

5. Maintenance needs

To keep your air purifier running in the best condition, you need to ensure that you replace the filters timely at the recommended interval mentioned by the manufacturer. If the unit uses multiple filters, you would need to change them at different times. For example, the HEPA filter may last for a year but the activated carbon filter lasts only for six months. The pre-filter may last as less as 3 months only.

When looking at different air purifier models with the intention to purchase, it is important to take into account the frequency and cost involved for filter replacements. The maximum life span for any filter is usually mentioned in the product specifications. To keep things simple, many models use combination filters and only one of them needs to be replaced.
