HEPA air purifiers may boost brain power in adults over 40 – new research

Using an in-home HEPA purifier for one month spurs a small but significant improvement in brain function in adults age 40 and older. That’s the result of a new study we co-authored in the journal Scientific Reports.

HEPA purifiers – HEPA stands for high efficiency particulate air – remove particulate matter from the air. Exposure to particulate matter has been connected to respiratory and cardiovascular illnesses as well as neurological diseases such as Alzheimer’s and Parkinson’s. Environmental health researchers increasingly recommend that people use HEPA air purifiers in their homes to lower their exposure to particulate matter, but few studies have examined whether using them boosts mental function.

We analyzed data from a study of 119 people ages 30 to 74 living in Somerville, Massachusetts. Somerville sits along Interstate 93 and Route 28, two major highways, resulting in relatively high levels of traffic-related air pollution. This makes it an especially good location for testing the health effects of air purifiers.

We randomly assigned participants to one of two groups. One used a HEPA air purifier for one month and then a sham air purifier – which looked and acted like the real thing but did not contain the air-cleaning filter – for one month, with a monthlong break in between. The second group used the real and sham purifiers in reverse order.

After each month, participants took a test that measured different aspects of their mental capacity. The test probed people’s visual memory and motor speed skills by measuring how quickly they could draw lines between sequential numbers, and it tested executive function and mental flexibility by asking them to draw lines between alternating sequential numbers and letters.

We found that participants 40 years and older – about 42% of our sample – on average completed the section testing for mental flexibility and executive function 12% faster after using the HEPA purifier than after using the sham purifier. That was true even when we accounted for factors like differences in the amount of time participants spent indoors, with either filter, as well as how stressful they found the test.

This improvement may seem small, but it is similar to the cognitive benefits that people experience from increasing their daily exercise. While you may not experience a sudden increase in clarity from a 12% boost, preventing cognitive decline is vital for long-term well-being. Even small decreases in cognitive functioning may be associated with a higher risk of death. https://www.youtube.com/embed/CKpg3qCMXi4?wmode=transparent&start=0 Studies increasingly show that air pollution can be detrimental to brain health.

Why it matters

Air pollution can negatively affect mental function after just a few hours of exposure. Studies show that air purifiers are effective at reducing particulates, but it’s unclear whether these reductions can prevent cognitive harm from ongoing pollution sources like traffic. Research has been especially lacking in people living near major sources of air pollution, such as highways.

People living near highways or major roadways are exposed to more air pollution and also experience higher rates of air pollution-related diseases. These risks aren’t encountered by all Americans equally: People of color and low-income people are more likely to live near highways or areas with heavy traffic.

Our study shows that HEPA air purifiers may offer meaningful health benefits under these circumstances.

What still isn’t known

Research shows that air pollution begins to affect cognitive function especially strongly around age 40. These effects may become increasingly prominent as people age.

HEPA air purifiers may therefore be especially beneficial for older adults. Our study did not explore this possibility, as fewer than 10 of our 119 participants were over the age of 60.

Also, our participants only used a HEPA air purifier for one month. It’s possible that longer durations of air purification may sustain or even increase the improvement in cognitive function we observed in our study.

Finally, it is unclear exactly how air purifiers improve cognition. Some studies suggest that exposure to particulate matter reduces the amount of the brain’s white matter, which helps brain cells conduct electrical signals and maintains connections between brain regions. The brain regions most harmed by air pollution are the ones that control mental flexibility and executive function, the same domains in which we saw improvements in our study.

We plan to study whether reducing particulate matter by using air purifiers is indeed protecting the brain’s white matter, and whether it could reverse some cognitive decline. We will explore that possibility by studying how levels of molecules called metabolites, which cells produce as they do their jobs, change in response to breathing polluted air and air cleaned by a HEPA filter.

The Research Brief is a short take on interesting academic work.

Room-by-Room Tips for Clutter-Free Spaces

(Feature Impact) A well-organized home isn’t about perfection. It’s about creating systems that make everyday life easier. When everything has a place, it’s simpler to maintain and keep clutter from creeping back in.

Experts often recommend tackling organization one room at a time, sorting items into categories like keep, donate or discard before finding the right storage solutions. If your home could use a refresh, start small and work your way through each space with these organization tips.

Entryway

A dedicated “drop zone” ensures items used daily don’t end up scattered throughout the house. However, the entryway is also one of the easiest places for clutter to pile up. To keep it tidy:

• Install wall hooks for coats, bags and backpacks
• Use a small bench or basket for shoes
• Add a tray or bowl for keys, sunglasses and everyday essentials

Kitchen

One of the most-used rooms in nearly every home, kitchen organization is key to making daily routines smoother. To stay organized:

• Clear unnecessary items off countertops
• Group pantry items by category, such as snacks, baking supplies and canned goods
• Store rarely used appliances in cabinets or a pantry

Living Room

Living rooms often serve many purposes, from relaxing and entertaining to working or studying. The key is creating storage that blends seamlessly with your decor:

• Use decorative baskets for blankets, magazines and toys
• Choose furniture with hidden storage like ottomans or coffee tables
• Keep remotes and small electronics in a designated tray or organizer

Bedroom

Your bedroom should feel like a sanctuary. Too much clutter can make it harder to relax and unwind. To maintain order:

• Keep only essential items on nightstands
• Rotate seasonal clothing to free up closet space
• Use under-bed storage bins for extra linens or off-season clothes

Bathroom

Bathrooms often have limited space, so smart storage solutions are essential:

• Keep countertops clear except for frequently used products
• Separate backup supplies from daily-use items, which should be stored for quick access
• Use over-the-door organizers for towels or extra storage

Home Office

Whether you work remotely or simply manage household tasks, an organized office helps you stay focused. To improve productivity and reduce distractions:

• Digitize or recycle unnecessary paperwork
• Use desk trays and organizers for supplies
• Create labeled folders or a filing system for important documents

Storage Areas

Garages, basements and storage rooms can quickly become catch-all spaces. A little planning can make them much easier to manage:

• Label bins for seasonal decorations, tools or sports equipment
• Use shelving and wall storage to maximize vertical space
• Keep an inventory list for larger storage areas

With a little planning and the right habits, a well-organized home becomes easier to maintain. Find more ideas at eLivingtoday.com.

5 Tips for Gardening with Kids

(Feature Impact) Gardening is a simple way to bring families together while simultaneously teaching kids hands-on lessons about nature, responsibility and healthy living. Whether you have a backyard garden, a few containers on the patio or are looking for a starting point, getting your children involved in planting and caring for plants can spark curiosity and create lasting memories.

To get started, consider these family-friendly tips:

1. Start Small

Begin with a manageable project, such as a few containers, a small garden bed or a single planter box. This helps keep the experience fun rather than overwhelming and allows children to see progress quickly.

1. Let Kids Choose the Plants

Giving your children a say in what goes into the garden can help build excitement and a sense of ownership. Ask them to pick a few colorful fruits, vegetables or flowers that grow quickly, such as sunflowers, cherry tomatoes, mint, sugar snap peas or marigolds.

1. Give Them Their Own Space

Kids feel proud when they have something that’s their own. Consider assigning each child a small plot, container or row in the garden. Let them be responsible for watering, planting and checking on their plants.

1. Use Kid-Sized Tools

Little hands typically work best with tools designed just for them. Small watering cans, lightweight trowels and child-sized gloves help kids participate safely and comfortably.

1. Encourage Creativity

Gardens don’t have to be all work. Add some fun to the process by adding artistic touches. Projects such as decorating pots, painting plant markers or creating a fairy or butterfly garden can keep imaginations engaged as well.
