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.

Stopping the ‘Silent Killer:’ How to Check, Prevent and Manage High Blood Pressure
Stopping the Silent Killer: High blood pressure poses significant health risks for people of all ages, but there are effective ways to both prevent and manage this “silent killer” by working with a health care professional to make lifestyle changes.
Stopping the ‘Silent Killer:’ How to Check, Prevent and Manage High Blood Pressure
(Feature Impact) High blood pressure poses significant health risks for people of all ages, but there are effective ways to both prevent and manage this “silent killer” by working with a health care professional to make lifestyle changes.
Hypertension, also known as high blood pressure, is when the force of blood flowing through blood vessels is consistently too high. This condition makes the heart work harder than normal and can damage arteries, increasing the risk of heart disease, stroke and other health problems.
High blood pressure is the leading risk factor for stroke and heart conditions such as coronary artery disease, heart failure and atrial fibrillation. Strengthening evidence also shows high blood pressure is linked to risk of cognitive decline and dementia, which is why the American Heart Association is working to increase awareness and encourage people to manage blood pressure. Protect your heart and brain both now and in the future with this information and wellness advice.
Who Can Have High Blood Pressure?
Anyone can develop high blood pressure, which is why it’s encouraged for everyone – in all age groups, including children and young adults – to have their blood pressure checked at annual physicals or wellness checkups. For those with a history of high blood pressure or risk factors for developing the condition, more frequent measurements may be recommended.
Major risk factors for high blood pressure include excess weight, diabetes, high cholesterol, smoking, lack of physical activity, alcohol consumption and a diet high in sodium and low in potassium.
Nearly half of adults in the U.S. have high blood pressure and many don’t even know it. Of those with high blood pressure, about 75% don’t have the condition under control. Because it typically shows no symptoms, it’s often called a “silent killer.”
How is Blood Pressure Checked?
To get the best blood pressure reading, sit in a chair with support for your back with both feet flat on the ground.
Use a validated, automatic, cuff-style, upper-arm monitor. Remove clothing over the arm that will be used and rest for at least 5 minutes. Extend your arm and support it at heart level while staying quiet and still then take multiple readings and record the results. Aim to measure at the same time each day.
For most adults, a normal blood pressure reading should be less than 120/80 mm Hg.
What Happens After a High Blood Pressure Diagnosis?
Recognizing and taking quick action to control high blood pressure can significantly lower the risk of severe health consequences, including heart attack and stroke, and improve overall health. If you’ve been diagnosed with high blood pressure, work with a health care professional to design a treatment plan that works for you. It may include lifestyle changes to your diet or activity levels or medication.
How Can High Blood Pressure Be Prevented or Managed?
Preventing high blood pressure is possible. Talk with a health care professional to create a plan that works for you, which may include small steps like eating a heart-healthy diet, staying active and maintaining a healthy weight.
For those diagnosed with high blood pressure, maintaining a healthy weight by staying active (at least 150 minutes of moderate activity per week) and eating a balanced diet rich in fruits, vegetables, lean protein and whole grains are important. Even losing 5% of your weight can help improve blood pressure.
It’s also important to reduce or avoid alcohol consumption and tobacco use. Consider stress-reducing activities, including meditation, breathing control or yoga. For many individuals, adhering to prescribed medications is essential to effectively control blood pressure and reduce the risk of serious health complications.

Room-by-Room Tips for Clutter-Free Spaces
Clutter-Free Spaces: A well-organized home isn’t about perfection. 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.
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.

Say ‘Yes, Please’ to The Grilled Cheese of the Year: Gooey Goodness with a Protein Punch
(Feature Impact) A grilled cheese sandwich isn’t just a lunchtime staple; it’s a beloved cultural icon. There is a universal magic in the combination of ooey-gooey cheese, golden bread and a little butter – but in 2026, this comfort food classic is getting a functional upgrade.
It’s also safe to say nostalgia is delicious and addicting, which is why Borden Cheese is sharing not one, but two, prize-worthy recipes, one of which packs a protein punch and another that’s a pure classic, perfect for spreading smiles and happy bellies.
Protein, Please: The Protein Powerhouse is the Grilled Cheese of the Year, and it’s easy to see why. It’s a protein-packed masterpiece designed for the modern appetite. Featuring a creamy, dual-cheese combo of mild cheddar and Borden Mozzarella Cheese Melts, the sandwich is melted over 5 ounces of tender sliced chicken breast and delivers more than 40 grams of protein and about 8 grams of fiber when paired with the right bread. Served with a tangy Greek yogurt and Dijon mustard “powerhouse sauce” and pressed between golden, crispy bread, this grilled cheese isn’t your ordinary melt. It has been transformed into a massive protein boost.
Tried n’ True: While modern flavors and trends are delicious, nostalgia is too. In fact, a whopping 20,000 fans cast their votes for America’s Favorite Grilled Cheese, asserting a fervor that’s unmatched when it comes to their perfect melt, and awarded The Classic the title of “America’s Favorite.” This comforting recipe pairs extra sharp melts with American singles on sliced white bread for a perfect, ooey-gooey bite that reminds you the cheese truly “makes” the sandwich.
