How to Reduce Indoor Air Pollution: Dr. Karen Lee’s Five Tips

How to Reduce Indoor Air Pollution

As winter approaches, many of us are getting our home maintenance done to prepare for the cold weather. And to prevent cold air coming in and to save energy, you might seal holes or cracks, caulk around the window frame, place draft dodgers on the window sills, wrap window air conditioners, and replace old sealants around the door frames. And some of you may even keep the windows shut entire winter in trying to keep your energy cost down. But if you’re like most Americans and spend over 90% of your time in your home and the car, you will be exposed to indoor air pollution. And by sealing your home airtight for the winter, you just vacuum sealed the pollutants inside too. Studies have shown an unfortunate connection between health problems – like Asthma and cardiovascular problems – and indoor pollution. So what should you do? Here are five tips on how to reduce indoor air pollution. But first, some facts on indoor air pollution.


While you might think pollution is worse outside — smog, ozone, or pollens, especially in summer – the truth is, indoor pollution in homes, offices, and buildings can be worse than the outside. The indoor air pollutants like lead, toxic gasses, chemicals, fire-retardants, radon, volatile chemicals, and carcinogens can be found in furniture, carpet, clothes, fragrances (health and beauty products), and cleaning solutions. Also, many pollutants are tracked from outside into the home on shoes, pet hair, and even our clothes. And if you have bought new furniture or bedding, they can be in new mattresses or furniture, flooring materials, or a new coat of paint on walls.

On average, American people spend more than 90 percent of their time indoors in homes, offices, gyms, schools and cars. Unfortunately, these indoor places are usually full of dust, dust mites, particles, chemicals, toxic gasses, mold, and microbiomes. You can read more about the 10 Common Toxic Chemicals to Avoid here, here, and here. And how to avoid them here. These toxins can enter our bodies from air and dust when we breathe and contaminated surfaces that we touch, and accidentally transfer them to our food or mouth with our dusty hands. And according to the Endocrine Society’s study, some of these chemicals can contribute to health problems like reproductive problems, obesity, cancer, hormonal imbalance, thyroid problems, cardiovascular issues. Furthermore, children are particularly affected by the indoor contamination because not only are they still developing but they are in close contact with the floor, crawling, playing on the floor, touching everything with their hands and putting them in their mouths. Even a little bit of exposure, if continued, can create health problems later on in life.

According to WebMD, microscopic dust mites (a major allergen) mold, and pet dander can create a highly allergic environment for those with allergies. So what should you do? Take these five easy steps and eliminate indoor air pollution as much as you can.


  1. Keep it out – don’t bring the outside pollutants IN by wearing shoes inside. Leave the shoes outside the door. Use a Welcome mat for people wipe their shoes clean before entering. Better yet, have your guests remove their shoes too. If you need to have workers come inside, offer them non-slip over the shoe booties (Amazon affiliate link) to use and dispose of them after use.
    Circulate the air – open the window at least once a day to exchange the outside air and inside air. Opening the window also reduces moisture to prevent mold. You can also use a dehumidifier to reduce humidity. Opening the window also lets good microbiome in to counteract the bad microbiome for healthier air inside.
  2. Keep out the smoke – no smoking inside the home. Period. Don’t burn food or use Teflon coated cookware that creates toxic fumes (PFOA). If you don’t have a vent, install a cooking vent that exhausts the air OUT and not just recirculates the air inside.
  3. Purify the air – use a quality air purification system like Intellipure (see more info below,) to filter out micro-fine particles.
  4. Fragrance-Free – do not use artificial fragrance in ANY products that can potentially contain thousands of chemicals – some are carcinogenic and some endocrine disrupting. Use fragrance-free detergents and fabric softeners. Use furniture polish, air fresheners, and sprays that are natural and void of artificial fragrance.
  5. Bring nature IN – use plants to filter the air. NASA studied how plants and what types of indoor plants can help filter the indoor air and found these helpful tips. So bring nature in and have indoor plants in your home. If you are sensitive to mold, though, be careful not to make the indoor air too humid as soil can contain mold.


My children have allergies to dust and dust mites. They also suffer from food allergies and the one way they exhibit their symptoms is Eczema. My son also suffers from Asthma when an allergic reaction occurs to environmental allergens. Recently, we found out my son is allergic to wool. And the carpet in his room is wool! Why did we install wool carpet? We thought it’s better than synthetic fibers. We thought wool would repel dust mites. We thought it’s naturally stain resistant. Well, we had our reasons in the right places, but we had no idea he was allergic to wool….and we wondered why he kept having flare ups. Obviously, the air filtration unit he had in his room wasn’t effective enough to filter out the fine particles from the wool carpet.

So when Intellipure asked me to do a review of their new fine particle air filtration machine, I was really excited to learn more. Not only is the product made in U.S.A. but the headquarters is located in upstate NY, my home state! So of course, I said ‘YES!” and they sent me a unit for me to try. As you know about my reviews, my opinion is my own and of course, I’d only write about products I believe in.

Intellipure In The Home

I will say right off the back, this unit is not cheap. But, you get what you pay for. In the past, I spent way too much money buying various air filtration units that turned out to be junk or even toxic for our health. Remember the Sharper Image ionizing air filter unit that created toxic ozone? Yea. I owned one of those until I smelled ozone in the room. I had to throw it out, wasting hundreds of dollars. I don’t even want to know how much money I’ve wasted on ALL the air filtration systems we had. So when you see a unit that’s at Bed Bath and Beyond or Brookstone, be careful what you read or hear. By just reading the product specs in the stores, you don’t know how effective they are. You have to talk to the manufacturer, or a salesperson and Intellipure answered every question I had.

Here is a list of reasons why I trust Intellipure.

  • Patented Disinfecting Filtration System (DFS) is superior to HEPA standards.
  • HEPA standard is for eliminating particles that are .3 microns, and DFS system is for .007 microns in size.
  • Combats all three pollutant categories – Micro-organisms, Volatile Organic Compounds (VOCs), and Particles
  • Captures 99% of airborne particles down to .007 microns in size, this includes ultrafine particles, virus, bacteria, fungi, and mold.
  • The machine has four multi-stage filters that capture various sizes of particles. The filters need to be changed once or twice a year from the company’s website.
  • Noise level – it has a “Sleep” mode option so you can sleep better.
  • Energy Efficient – Only uses 1 watt per hour when on low or sleep mode
  • Removal of airborne odor
  • This system is currently used in hospitals, medical clean rooms, government buildings, and military applications.
  • And because the parent company has been around for decades in this industry, I trust their commitment to manufacturing safe and effective machine for our health.


  • Founded in 1981
  • 35 years of experience in indoor air quality solution
  • Over 25 patents in 40 countries
  • Worldwide distribution
  • Products made in U.S.A. by people and not by machine

Here is a video about the Intellipure system that demonstrates what it does better than I can.
