Before hitting the internet and shopping for a new air filter for your nursery, it’s best to understand precisely what HEPA filters are. With this knowledge, you can make more informed shopping decisions. 

According to the United States Environmental Protection Agency (EPA) website, the term “HEPA” is an acronym that stands for “high-efficiency particulate air.” Notably, “this type of air filter can theoretically remove at least 99.7% of dust, pollen, mold, bacteria, and any airborne particles.” With this helpful information from the EPA, we can assume that all HEPA filters have the same primary function: clean the air by trapping suspended particles. However, not all HEPA filters are created equal.

As we have seen, you can’t overstate the importance of clean air in a nursery environment. In order to protect your child’s health, it’s recommended that you take the appropriate steps to reduce and eliminate indoor air pollution. We put together this list of the five best HEPA air purifiers for nurseries to help with this process. 

When shopping for a HEPA filter for your home, we recommend using the information in this guide in conjunction with the product specifications. In doing so, you can match important criteria such as purifier capabilities and the square footage of your nursery. After all, you want to make sure that the purifier is not too big or small for the intended room.

Where Should I Place a HEPA Filter in the Nursery? 

Once you have decided on the best air purifier for your budget and needs, it’s time to figure out where to place it. The goal for putting the HEPA filter in your nursery is to find a convenient and functional place while also not being an eyesore. 

When you run the air purifier in your nursery, you must do so with doors and windows closed. This way, you are not pulling in air from outside sources. This notion is crucial concerning doors between rooms. Because if a door is left open while the purifier is running, it will pull more air than is rated for and not work effectively. 

Be sure that the HEPA filter is not in a tight corner or closet. Similarly, do not position it in extremely close quarters with furniture. Each air purifier model features intake ports and exhaust ports. These ports work in conjunction with one another to pull dirty air into the HEPA filter and push it back out into the room. If you place the air purifier in a tight place, such as between a bed and a wall, you will block one of these ports and keep the system from working correctly. 

You will want to position the HEPA filter in an area standing independently in the nursery. In doing so, the purifier can work at its best to circulate air in the room effectively. However, be sure you don’t place it somewhere where you will trip over the unit. If you run into the HEPA filter whenever you check on your baby, it likely needs to be moved. 

If you are still unsure about the best place to position your chosen air purifier, please refer to product instructions for more guidance.
