Tip 1. Balance Air Purifier Use with Open Windows

Have you ever wondered if you can use an air purifier with the windows open? Yes, you can, but there are certain points to consider. Air purifiers are designed for closed spaces to filter indoor air and trap contaminants. However, you may keep your windows open to ventilate and allow odors to escape. Yet, according to recent studies, air purifiers can reduce PM2.5 with windows slightly open, depending on how good the outdoor air quality is.

If you are to open your windows, use purifiers designed for larger rooms and for smaller spaces, and keep your windows closed for better results. Position the purifier away from windows to avoid pulling in unfiltered outdoor air. Ideally, you should balance purifier use with periodic ventilation when outdoor air quality is good.

Tip 2. Move Essential Oils Away From Your Air Purifier

Do not use essential oils in an air purifier, as standard purifiers, especially those with HEPA filters, are not designed to handle essential oils, which can clog and damage filters. You should use a separate diffuser alongside the purifier for oils. Keep them apart to prevent scent from interfering with the purifier. Avoid using low-quality oils that may release synthetic toxins into the air. You are advised to check the purifier’s manual for oil compatibility to avoid damage.

 

Tip 3. Pair Your Air Purifier with a Fan for Enhanced Airflow

Suppose you’re wondering whether an air purifier can double as a fan. In that case, an air purifier’s primary job is filtration, meaning it pulls in air to clean it of pollutants and then releases purified air. While this process does create some airflow, it’s usually gentle circulation, designed to draw air through its filters, not to cool a room. A traditional fan, on the other hand, is built for cooling; it moves a large volume of air rapidly to create a breezy, cooling effect.

For optimal air quality and comfort, it is recommended pairing your air purifier with a separate fan. Directing the fan’s airflow towards your air purifier’s intake can significantly enhance its efficiency, helping it capture pollutants more effectively by guiding more dirty air into the filtration system.

However, some innovative devices, like the Dreame air purifier, offer more versatility. With its dual-way air outlets (upward and forward), it can indeed function as an air purifier, a circulation fan, or even just a fan on its own. Additionally, it offers the benefit of warming the air on a chilly day, making it a truly multifunctional addition to your home.

Tip 4. Run Your Air Purifier Continuously (24/7)

Running your air purifier continuously, 24/7, is not only safe for the device but also highly recommended for maintaining consistently clean and healthy indoor air quality. Pollutants like dust, pet dander, volatile organic compounds (VOCs), and allergens are constantly being introduced into your home, even when you’re not actively doing anything.

Leaving your air purifier on continuously ensures it can capture these particles as they appear, preventing them from accumulating in your environment. This is especially beneficial when you’re away from home, as it ensures you return to a space with cleaner, fresher air, ready for you to enjoy. Consistent operation is key to truly optimizing your indoor air.

 

Tip 5. Adjust Your Air Purifier for Specific Situations

Your air purifier shouldn’t be set on a single setting, as different activities introduce varying types of pollutants. When cooking or frying, increase the fan speed to manage smoke and odors. Similarly, during heavy cleaning, put the fan speed to maximum to capture dust and allergens. You must be careful not to run the purifier on a higher setting continuously during peak pollen season.

Modern air purifiers automatically adjust their speed, so consider Dreame air purifiers, which offer multiple modes suitable for various situations and can automatically adjust according to the environment.

Tip 6. Strategize Air Purifier Placement in Multi-Room Homes

If you have a large house with multiple rooms and only one or a few purifiers, you need to place them strategically to improve indoor air quality effectively. Place the purifier in the room where the most time is spent, e.g., the bedroom at night or the living room during the day. Dreame air purifier features directional airflow, which automatically detects your body movements and sends filtered air towards you.

 

Avoid Blocking Your Air Purifier’s Airflow

Do not place the air purifier in the corner, as it is designed to purify in open spaces and should be positioned at least 12-18 inches away from walls or furniture to ensure unobstructed airflow. You should avoid corners, cramped spaces, or areas blocked by objects like plants or decor.

However, the Dreame AirPursue PM20‘s air intake surrounds the body 360 degrees and allows it to operate at maximum efficiency regardless of its placement.

 

Tip 7. Daily Clean and Maintain Your Air Purifier

Air purifier maintenance is important. While you may need to replace the air filter periodically, certain parts of the purifier can accumulate dust and debris, which can affect its performance and lifespan.

 

Conclusion

Air purifiers are essential for maintaining suitable air quality inside your home. They are designed to filter air and trap pollutants. They cannot be used as a fan or with essential oils, as they may clog the filters. Interested in buying an air purifier? Check out Dreame air purifiers to learn more.
