Do We Really Need Air Filters? (+ Reviews)


There is some discuss as to either atmosphere filters are unequivocally required for a healthy home. True, we can do a lot for your indoor atmosphere with a few well-chosen indoor plants and it is a many healthy and inexpensive approach to freshen indoor air. But given indoor atmosphere is some-more soiled than outward air, and with all of a chemicals and off-gassing materials used in home building and furnishings today, atmosphere filters and purifiers can usually help… as prolonged as we squeeze a right one.

Indoor Air Pollutants

Whether it’s seat off-gassing or cleaning products used around a house, indoor atmosphere peculiarity is mostly worse than outward air. Even when we’re regulating a safest products we can, it’s formidable to get divided from these chemicals and toxins entirely. Add in a fact that many of us have to keep a windows hermetic for months during a time when it’s too cold or prohibited outside, and indoor atmosphere wickedness is unavoidable.

Some of a common sources of indoor atmosphere wickedness are:

  • personal caring and cleaning products
  • tobacco fume (even what’s brought in on someone’s clothes)
  • gas ranges
  • water-damaged materials
  • furniture (pressed timber in particular)
  • new building materials (new flooring, carpets, remodeling, etc.)

And here’s what these sources are contributing to a indoor atmosphere we breathe:

  • asbestos
  • biological pollutants
  • carbon monoxide (CO)
  • formaldehyde
  • lead (Pb)
  • nitrogen dioxide (NO2)
  • pesticides
  • radon (Rn)
  • mold

All of these indoor atmosphere pollutants get into a lungs and disseminate by a body… not an ideal situation, generally where immature kids and babies are concerned.

Health Effects of Indoor Air Pollution

According to a Environmental Protection Agency (EPA), indoor atmosphere wickedness can means evident symptoms such as:

  • irritation of a eyes, nose, and throat
  • headaches
  • dizziness
  • fatigue

Long-term, asthma symptoms competence uncover adult or worsen. Studies also indicate to contingent respiratory diseases, heart disease, and even cancer.

Research published in a biography Neurotoxicology shows that childhood diagnosis of asthma, allergies, Asperger’s and Tourette’s competence be related to bearing of some indoor atmosphere pollutants.

A 1996 investigate also indicates long-term bearing to indoor pollutants presumably causes Multiple Chemical Sensitivity (MCS). MCS is a illness (not famous by medical organizations) where a studious reacts to chemicals in a environment. Often a symptoms are fatigue, mind fog, nausea and headaches. While it competence not be strictly recognized, thousands of stories from chemically pang people advise some-more studies are needed.

Reducing Indoor Pollution

Though we can’t get divided from pollutants entirely, we can minimize a volume of indoor pollutants in a homes. An apparent place to start in cleaning adult indoor atmosphere peculiarity is to revoke a source of pollutants. Building materials, furniture, mattresses, cleaning and personal caring products, and atmosphere fresheners can all minister to bad atmosphere quality. Here are some ideas for shortening a sources of bad atmosphere quality:

  1. Replace aged seat and mattresses with reduction poisonous choices.
  2. Replace required personal caring and cleaning products with healthy ones. (I competence know where we can find a few recipes for homemade home cleaning products or healthy DIY beauty treatments!)
  3. If building or rehabbing your house, try to use non-toxic materials from creditable “green” companies.

A good out-of-date airing of a residence by opening windows frequently competence help, though if we live in an area with a lot of atmosphere wickedness or humour from anniversary allergies, this competence not be a good resolution for you.

Ways to Filter Indoor Air Naturally

There are several ways to purify adult a atmosphere and urge atmosphere peculiarity in your home. we use a multiple of all of them:


An easy and cost effective approach to make an impact on a atmosphere peculiarity in a home is to use plants. Almost any plant will assistance purify adult indoor atmosphere (they catch gases — including CO2 — by their leaves) though some are softened during it than others. Some of a best plants for cleaning indoor atmosphere are:

  • bamboo palm
  • lavender
  • aloe
  • tulip
  • English ivy

If crawling toddlers make we wish for another option, cruise unresolved plants on a wall (or relocating on to a subsequent few suggestions).

Negative Ions

Another approach to purify adult indoor atmosphere is by disastrous ions. Many toxins are unequivocally charged. Both beeswax candles and Himalayan salt lamps purify a atmosphere by emitting disastrous ions that insert to toxins and mislay them from a air. Beeswax candles and salt lamps are also both relaxing and beautiful, creation them a good further to a healthy home. It is critical to note that conjunction of these solutions creates a lot of disastrous ions and competence not do many opposite some-more soiled air.


Did we know a V in HVAC stands for ventilation? That’s how critical it is! An HVAC complement that’s operative scrupulously should take caring of movement for we (but make certain it’s been serviced recently!)

If your home is exhilarated with timber or other choice to an HVAC system, movement is still important. When possible, opening a window and vouchsafing in some uninformed atmosphere can do wonders. If it’s too cold outward tighten off one room and open a windows in that room for an hour or so. Then when it’s full of uninformed air, tighten a windows and open a doorway to a rest of a house. The uninformed atmosphere will disseminate by a residence though won’t impact a heat inside (much).

Again, if we have anniversary allergies or live in an area with controversial atmosphere quality, this competence not be an choice for you.

Air Filters

And finally… yes, atmosphere filters are a good approach to purify a atmosphere in a home! With all a options out there, here are a need-to-know contribution on atmosphere filters I’ve schooled by trial, error, and many research.

Why We Still Need Air Filters

Even after all of a other stairs are taken to revoke toxins in a home, a good atmosphere filter is value a investment. Just think, presumption we spend half a time sleeping (or, if you’re a mom, a entertain of your time!) regulating an atmosphere filter even only in a bedroom can revoke bearing to airborne toxins by 50%.

Do Air Filters Work?

Air filters do have a certain impact on a volume of toxins in a air. One investigate found that atmosphere filters private some-more than 70% (and as many as 95%) of pollutant particles in a air. Other studies advise that due to a reduced contaminants in a air, respiratory and vascular (heart-related) symptoms improved.

There aren’t too many downsides to regulating an indoor atmosphere filter, honestly, but a few things to keep in mind: If atmosphere filters are in HVAC systems though a systems are moldy or have other allergens, a atmosphere filter competence not be assisting you. It’s also not loyal that a good atmosphere filter reduces a need for visit powdering and vacuuming (sorry!), that is an critical means of stealing all yukky chemical particles and allergens from a home.

Different Kinds of Air Filters

There are many forms of atmosphere filters accessible on a market, though they all tumble into one (or more) of these categories.

Ionic Air Filters

Ionic filters use electrical assign to mislay particles from a air. This kind of filter produces disastrous ions that attract particles in a air. As mentioned above, beeswax candles and salt lamps work in a identical way.

Carbon Air Filters

Activated CO can catch odors and particles in a air. Carbon is utterly good during trapping odors like cigarette smoke.

UV Light Air Filters

UV light atmosphere filters mislay impurities by exposing a atmosphere to a UV light. The UV light neutralizes many CO formed organic compounds (like mold and bacteria).

HEPA Air Filters

High potency particulate interesting filters (HEPA) can mislay adult to 99.97% of particles in a air, creation them a bullion customary for atmosphere filters. HEPA filters work in 3 ways:

  1. HEPA filters prevent particles as atmosphere flows by a filter. Particles that are tighten to a fiber in a atmosphere filter are held and trapped.
  2. Larger particles can’t adjust to a changes in atmosphere upsurge in a filter and run into a fibers (and get stuck).
  3. Microscopic particles pierce in a random, zig-zag like settlement (because they hit with other molecules). Because of this and a approach a filter is designed, they have a aloft possibility of being held by a fibers.

Zeolite Air Filters

Zeolite is a vegetable that is unequivocally absorbent. It is done adult of aluminum, hydrated silicon compounds, and oxygen and can trap poisonous gases and odors such as formaldehyde, ammonia, and CO monoxide.

These filters can be used alone or in multiple with one another.

Best Air Filters

There are so many atmosphere filters accessible on a marketplace it can be tough to know that ones are unequivocally good and that ones aren’t. Filtering by a options (ha!), it seems a multiple of whole complement filtration (a filter in a HVAC system, for example) and internal filtration (a stand-alone atmosphere purifier) is best.

I possess a Austin atmosphere cleanser from Radiant Life and run it in a family room. we also recently detected a Air Doctor atmosphere filter and bought them for a bedrooms for a atmosphere peculiarity sensor underline and reduce cost point. (It’s also utterly a bit quieter, that is nice.)

Austin Air Filter

I adore a Austin atmosphere filter since it’s impossibly high peculiarity and is endorsed by allergists. It combines several of a atmosphere filtering methods described above, including activated carbon, zeolite, and HEPA record to discharge a many pollutants. Austin atmosphere filters are also designated as “medical grade” and mislay particles as tiny as .1 microns (a micron is 1 millionth of a meter).

This atmosphere filter is also intensely durable (vs. something that will quit operative and finish adult in a landfill in a year). Made of plain steel, a Austin atmosphere cleanser won’t off-gas like cosmetic purifiers and it even comes with a 5 year guarantee!

AIR Doctor Air Filter

The AIR Doctor atmosphere filter is allied in opening and peculiarity to a Austin atmosphere filter though has a somewhat reduce cost indicate (and I’ve been means to negotiate it for many reduce for a singular time).

This filter also uses a multiple of a high-grade HEPA filter along with a carbon/gas trap/VOC filter. Like a Austin Air it is a 100% hermetic complement and removes even ultra-fine particles smaller than .1 microns. This means it removes unequivocally tighten to 100% of particles.

One advantage this filter has over a Austin Air is a built-in sensor that tests a peculiarity of a atmosphere and adjusts a filter to a scold turn of filtration.

I conclude that a AIR Doctor filter is a tad quieter due to softened fan technology, and they have limited-time understanding they’re charity to Wellness Mama readers.

Do We Really Need Air Filters?: Bottom Line

The brief answer is: Yes! Though other strategy for combating domicile toxins (like houseplants, beeswax candles, and shortening pollutants) unequivocally help, atmosphere filters are required for a purify indoor atmosphere environment. Allergy sufferers and children generally will benefit.
