Those who live in largely populated cities already know that air quality can be an issue. It’s to blame for around 4.2 million annual deaths worldwide, as pollution contains harmful carcinogens like solvents and metals. It’s no secret that populations continue to expand — and more human activity means worsened air quality.

There are many ways to combat air pollution, but we can’t expect solutions to work immediately. That’s why air purifiers have become increasingly common. With continued innovation, we can expect sustainability to play a role in future air purifier technology, too.

What Causes Air Pollution?

Mainly, poor air quality stems from energy production and use. That’s due to how we burn fossil fuels like oil and coal to power our homes, businesses and vehicles. This process creates harmful nitrogen oxides, which lead to air quality concerns such as acid rain. It’s responsible for emissions that worsen climate change, too.

Health Effects of Air Pollution

It’s no surprise that such deadly pollutants have implications. Research points to how poor air quality contributes to health concerns, including heart and lung disease. Those who have specific preexisting conditions are especially at risk. There are even mental wellness problems, as people who live close to air pollution sources like factories experience increased stress and anxiety.

Why Air Purifiers Make a Difference

Because people mainly spend their days inside, air purifiers can make a difference. These areas often contain unsafe air due to paint, pets and other contributors, so we need to find ways to improve the places where we spend the most time. That’s why air purification matters.

Essentially, air purifiers are appliances that draw in air. They run it through multiple filters to remove dust, odors and other airborne particles that can harm your health. Then, the machine releases the clean air back into the room. These systems also help maintain humidity levels.

How Solar and Other Renewable Energies Can Help

There’s a reason why renewable energy has a mostly clean reputation. Resources like solar and wind don’t emit any harmful pollutants or gases that harm the environment. They also regenerate, which means we can theoretically use this method of power forever.

These capabilities make them the best option for the future — and now, we can combine renewable energy’s benefits with air purification. Recently, technology has emerged to support solar-powered air purifiers. Worldwide, people have started to use portable devices to purify the air in their cars.

Initiatives to support such machines for household and business use continue to gain popularity. It’s an effort that might take several years to perfect, but there’s a demand for them, especially in remote areas where buildings can’t connect to power grids. These systems currently use electricity before switching to solar when the mains switch off.

Aside from commercial-scale solar-powered air purifiers, we might soon be able to use smaller devices without any need for electricity. Companies like Filtron have taken to crowdfunding sites to gauge interest in solar-powered machines you can use to filter air at home. These compact gadgets could be our best bet in fully linking solar to air purification.

All in all, there’s still progress to be made. However, we can expect continued developments in eco-friendly methods to purify the air we breathe. It may not be too long before we can use building-wide air purification systems powered by solar and other renewable resources.

Future Innovations Could Mean Cleaner Air for the Planet

Increased human activity means we need to find immediate solutions for air pollution. As we do so, we must prioritize sustainability, or we’ll create further implications. That’s why solar-powered air purification methods look especially promising.
