Have you ever thought about the air in your home and whether or not it’s clean and breathable? We become so accustomed to the air around us that we don’t consider whether or not we could make it cleaner.

With a large number of benefits to cleaner air in the home, such as improved respiratory function, purifying the air indoors gives us a better quality of life. In this guide, we will explore how to purify air in your home naturally.

We often think about the air outside being polluted and unclean, but do we consider how much of the air indoors is also contaminated?

It might be shocking to know that the air inside our homes is five times more polluted than the air outside and includes health risks such as nasal and throat irritation, eye soreness, and energy problems, such as headaches or fatigue.

Purification can give us a breath of fresh air with many benefits to our health and lifestyle.

Benefits of Using Natural Way Air Purifiers

No Electricity Usage

Purifying our air with a dehumidifier or a cheap electric air purifier can ramp up our electricity bills and cause us to spend more than we need to. Using natural, simpler ways reduces the need to spend the extra money and improves the air quality all in one!

Reduces Moisture levels

Moisture is the leading cause of mold and mildew buildup; mold spores are brought into our homes and grows in an area that is poorly ventilated or damp.

Natural purification eliminates a higher level of moisture, and natural plant air purifiers explored below, absorb the moisture, giving us fresher, more breathable air from the comfort of our own home.

Removes Bacteria, Pollutants & Allergens

The air is filled with irritants that can enter our system when we breathe. Allergens can slip through and cause us to cough and sneeze. Bacteria can cause infections. The pollution from our everyday objects, such as a gas stove, can affect our health in the long term.

Natural purification can give us ease of mind as they clean the air we breathe every day. Alternatively, get yourself an air purifier built for dealing with allergies.

8 Natural Ways to Purify Air at Home

1. Indoor Plants

A natural air filter, indoor plants absorb pollution from the air and release fresh oxygen.

Houseplants work well for people with respiratory problems and eases symptoms.

Recommended indoor plants for the best air quality include monstera deliciosa (swiss cheese plant), bromeliad, anthurium andraeanum, (pictured), and epipremnum aureum, or ‘Devil’s Ivy.’

2. Proper Ventilation

This isn’t as simple as opening windows as this allows more pollutants and allergens to flow in. Consider a trickle vent that cycles and allows cleaner air into our homes for us to breathe. An exhaust fan actively carries the polluted air outside, which could be better for a kitchen, carrying the highest level of air pollutants in our homes.

3. Salt Crystal Lamp

Salt lamps actively pull in the air around us and neutralize it. They are particularly useful when it comes to increasing your productivity as the toxins in the air can make us feel lethargic or give us mental blocks. Users of salt lamps generally report feeling more creative or alert, with more clean oxygen getting into their systems.

4. Beeswax Candles

If candles are something that you like, consider owning beeswax candles. They burn slower than a regular candle, meaning they don’t release any unburnt toxins into your air.

They also produce a natural honey scent, which means they aren’t filled with perfumes or fragrances that could release more pollutants.

Beeswax also neutralizes contaminants, giving us cleaner air.

5. Activated Charcoal

This is charcoal that’s undergone additional heating processes. It is a very strong absorber and takes in the toxins from the air while also being completely odorless. Activated charcoal deactivates once full, as it contains tiny pores that intake the toxins. Leaving it outside for an hour every month should reactivate the charcoal.

6. Essential Oils

Essential oils are clinically shown to kill airborne bacteria with a 99.96% success rate. Oils include:

  • Lemon
  • Tea tree
  • Clove
  • Pine needles

Simply add them to detergents or soap around your home, and they release through the air for natural purification.

7. Purifying Curtains

These are curtains that contain mineral coatings on the fibers and are activated by light, saving your electric bill. It doesn’t need replacing and actively breaks down the air pollutants in your home. Combined with blinds, they can make the process more practical and attractive.

8. Ceiling Fans

If you have an existing ceiling fan or are looking to install one, these can be an excellent option. They can be attached to your current fan with nothing but a screwdriver or installed easily. Purifying fans send the air through filters, and it is released into a room with a cleaner and better quality for us to breathe.

Common Indoor Air Pollutants

  • Carbon Monoxide
    Carbon monoxide is a byproduct of burning gasses and filters into our homes if the area (such as a boiler) is not properly ventilated. It is invisible and odorless and causes fatigue, headaches, nausea, confusion, and at high concentrations, death. If you suspect a carbon monoxide leak in your home, call a professional.
  • Formaldehyde
    This gas is released from objects in our home, commonly from items containing plywood or foam installations. Or they can come from drapes, fabrics, or wallpaper. It causes eye, nose, and throat irritation and increases in very humid rooms. See air purifiers for Formaldehyde here.
  • Radon
    Found everywhere, radon is formed by the breakdown of uranium in soil and rock. It seeps through cracks, dirt floors, and drains or through water, releasing it into the air. High levels increase the risk of lung cancer. All homes must be tested for high levels of radon.
  • Environmental Tobacco Smoke
    Secondhand smoke is from the exhale or side stream of cigarettes and is just as dangerous as regular smoking. It causes irritation and can lead to an increased risk of lung cancer or bronchitis. Quitting is the best method of removal from your home. A separate smoking area is also effective, but not completely.
  • Mold
    A natural allergen, mold spores attach to damp areas indoors and grow under humid and moist conditions. Mold gradually destroys an object it grows on. It can cause headaches, coughs, or eye irritation, and can even trigger an asthma attack.
  • Lead
    Lead was banned in 1978, so it is usually found in older homes. It is released through chipping paint or a disturbance, causing it to release. Health effects are severe, including brain damage, anemia, or kidney damage from high exposure.
  • Asbestos
    Asbestos is also banned from homes but is still found in thousands. It is released into the air when it’s disturbed from the walls or roofing, and the health effects can lay dormant for years before forming into diseases.
