We believe that our home is the safest haven for our kids and loved ones. Little do we realize that this sanctuary is often filled with harmful household chemicals that can make the air indoors more harmful than outdoor pollution. This is where the best air purifier for VOCs and Formaldehyde comes into the picture.

Most people consider air purifiers as a tool for removing dust, pollen, dander, and tiny particles suspended in the air, however this is just one part of the story. Some models are powerful enough to not only deal with the visible particles but also the invisible pollutants such as toxic gases or VOCs and formaldehyde.

VOCs stand for volatile organic compounds and they are a class of chemical compounds that become airborne close to room temperature. Formaldehyde is a type of chemical present in resins and adhesives used for making products such as laminate countertops and engineered wood products.

These compounds have the tendency to vaporize under room temperature and pressure conditions, causing them to build up in the air. They can have a detrimental effect on your family’s health. Therefore, it’s necessary to choose a high-quality air purifier capable of removing formaldehyde and other VOCs.

In this post, we have reviewed some of the top air purifiers for VOCs and formaldehyde, along with a comparison between products to help you choose. After reviewing dozens of products, we feel that the Hathaspace Air Purifier (learn more) is a good choice for someone looking to purify a small area, with 5 filters and a noise level of less than 18 decibels.

If you need a purifier with large coverage capacity, get the Austin HealthMate Plus which comes with a 5-year warranty. Although slightly more expensive, it lasts longer and delivers a remarkable performance in keeping your indoor air clean..

5 Key Things To Consider Before Buying An Air Purifier

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

If you have respiratory issues, asthma, or allergies, you may want to look for a product that specifically helps in managing your symptoms. We suggest that you consider an air purifier that exchanges air at least once per hour. ACH values indicate the number of times a device purifies air within an hour. The standard sizes include small, medium, and large rooms, and the whole house.

2. Type of filter

The quality of the 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% of airborne particles as small as 0.3-microns in 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 odors. If you are concerned about bad odors, choose a device that includes an activated carbon filter along with true HEPA filter. We also suggest that you choose a product that includes a pre-filter to extend the lifespan of the 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 even more useful. Some of the additional features you may want to consider 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 higher-end products, 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 to keep an air purifier in the bedroom or living area as this is where the family spends most of their time. Even if you buy a portable device, it can only purify one room at a time, so you may want to buy multiple devices to meet your needs. Alternatively, you may prefer to buy a device with caster wheels or handles to move it from one room to another with ease.

Another popular option these days is a whole-house air purifier. These devices are typically connected with HVAC systems to purify 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 regularly 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 only last as little as 3 months.

When looking at different air purifier models, 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.

Therefore, we suggest that you purchase an ozone-free UV air purifier like the Hathaspace Smart True HEPA Air Purifier.

How long do VOCs usually last?

Some types of VOCs such as those released by a fresh coat of paint may dissipate quickly or may stick around for up to six months after application. However, there are other sources such as particleboard that may continue to release gases for 20 years or even more.

What are other ways of removing VOCs?

Small changes can bring a big difference is lowering the level of VOCs inside your home. Start by choosing natural products instead of commercial ones, such as cleaning solutions and room fresheners. Add more ventilation to your home by opening a window or installing an exhaust fan.
