If you live or work near a busy road or highway, there are many things that can, unfortunately, disrupt your peace and tranquility. It isn’t just the roar of engines or the wail of sirens that can cause a problem, but also the quality of the air you breathe. Traffic pollution is a serious issue that may affect your health in more ways than one. It’s not just the air in your home that’s affected by traffic pollution. Many of us spend hours each day commuting by car, by public transport, and by walking, exposing us to those harmful toxins produced by traffic.

Major health consequences of traffic pollution include:

  • The onset of asthma in children
  • Heart attacks
  • Increased risk of dementia
  • Multiple Sclerosis (MS)

The good news is that investing in an air purifier can reduce the likelihood of both you and your family suffering from these unfortunate conditions. Many units are also portable which means you can take them with you to work or on vacation trips. Effective purifiers successfully capture harmful airborne particles and eliminate gases and odors. This allows everyone to breathe the freshest and highest quality air.

Before you invest in a purifier, it’s helpful to think about your budget and room size. The CADR (Clean Air Delivery Rate) of a system lets you know how much square footage it will clean per hour. The Coway Airmega 400 is designed for large rooms and cleans the air a minimum of two times per hour. But if you’re looking for something to use while working in a small space or even during car journeys, the Airdog FitAir is suitable for areas of up to 25 square feet.

To ensure we found the best purifiers to meet your needs, we used consumer reports analysis to remove any fake reviews. This means that all our recommendations come from genuine consumers like you who have used these models. We have also committed to choosing products that contain True HEPA/H13 and activated carbon filters as these capture the greatest number of harmful airborne particles.

FAQs About Air Purifiers for Traffic Pollution

Is your health more at risk living near a major road or highway?

Roadway traffic can cause air pollution, so anyone living, working, or going to school near major roads has a higher chance of experiencing health problems related to that pollution. There are known health effects related to road exposure such as cardiovascular disease, childhood leukemia, impaired lung development in children, and even premature death.

Alongside that, this exposure may lead to asthma onset and aggravation. Besides the pollution itself, living near major roadways can increase your risk of developing neurological disorders. This includes Parkinson’s, Alzheimer’s, and multiple sclerosis (MS). Road noise can also play a role in developing potential health problems.

What do I need to consider when buying an air purifier for pollution?

When it comes to protecting yourself from air pollution, you need an air purifier with the right filters. Having a HEPA filter is useful, but you also need to focus on removing those airborne gases. To do so, look for a purifier with an activated carbon filter. An activated carbon filter not only absorbs those harmful gases but locks them away so they won’t bother you again.

It’s important to see the type of activated carbon filter inside a purifier, however. Some may only have a small filter, so the effect may be minimal when tackling the issue at hand.

Are air purifiers capable of capturing vehicle exhaust fumes?

There is particulate matter (PM) found in vehicle exhaust, more so from diesel trucks. So, an air purifier with high-efficiency particulate air filters can be effective at removing that from the air. It’s also been shown that a reliable HEPA filter should go a long way in neutralizing other airborne particles caused by traffic. This includes aerosols like tobacco smoke and fungal spores.

Which Air Purifier is Best for You?

If you live in an area that experiences regular air pollution such as by major highways and roadways, then having an air purifier to help with those harmful airborne particles can only benefit your health. A quality purifier with both a HEPA filter and an activated carbon filter can capture and remove traffic-related particles, making the air around you healthier and easier to breathe in. Once you discover purifiers with the right filters, you can focus on narrowing things down by your budget and by the size of the room you wish for it to work in.
