Why do air purifiers smell? How to remove the smell from the purifier?

Why do air purifiers smell?

The smell comes from the ozone. Ozone is an unstable gas, so when it comes in contact with other unstable gases in the air, like peroxide and bacteria, they react to form new compounds.

That's why ozone smells so bad-it's trying to warn us that it's dangerous! Ozone can also react with other chemicals in the air to create volatile organic compounds (VOCs). These VOCs are what give your house that "new car smell." Sorry!

That's why many of the bad fumes you notice when you first turn on your air purifier will go away after a few hours or days of use.

Also if the filter needs cleaning. Odors may come from the wet or dirty filter media. A little clean filtering material with most commercial air purifiers can eliminate this odor.

How to make air purifiers stop smelling

You can mask the smell with air freshening spray, or use air filter to trap the unwanted odors.

What you can do to make air purifiers stop smelling:

  • Put a portable air freshener inside your electric air purifier, and the smell of the ripened fruit will be gone.  You can also use a diffuser or an oil burner to fill your room with a soft fragrance.  You've just had a "fill-up" from your air filter!  If you have an electronic air filter, it has its own built in diffuser.  These are especially nice for those who live in small apartments that have no windowsills or doors that can open or close.
  • Buy a new filter and put it in your air purifier.  If you buy a new filter, you won't have to buy another one next month.  It's like using a money-back guarantee on an electric appliance that looks expensive!  You can usually get high quality filters for about $10-$35 and last you 2-3 months of average use, depending on how often you need to change them out.
  • Use mint essential oil or powder to freshen the house.
  • Use baking soda or vinegar in your air purifier, and freshen your air daily (or weekly, depending on the type of air purifier).
  • Change the pre-filter on your air purifier, and put a new pre-filter in your CO2 filter.  This will help to prevent the peroxide and bacteria from forming hazardous chemicals.

Why do air purifiers smell like burnt wires

This is usually from the burning of dust inside your air purifier. Most of us will eventually notice this smell, and it's usually caused by long-term dust accumulation on the electrical heater element of your air purifier.

What happens is that dust will accumulate on the element, and when you turn your unit on, it will heat up rapidly. As the dust heats up, the tiny particles of dirt will begin to melt and attract each other. When they come into contact with each other they will stick together creating a more solid form of dust that is also more volatile than dust in general due to being heated up.

Air purifiers are designed to reduce the amount of toxins that are in the air

An Air Purifier will normally make the room smell much better than before you used the Air Purifier. This is because the Air Purifier is meant to filter out smoke, odors, and other toxins from the surrounding air.

Air purifiers produce good smells instead of bad smells

A lot of people feel that their indoor air can actually smell cleaner after using an air purifier then before using one, but they don't necessarily know why that is.


They are made to remove germs, dust, bacteria, allergens, mold, viruses, and odors

Most purifiers produce a fresh scent (not only the ozone scent) which is surprising to most people because they are not familiar with what an ozone generator or other different chemical smells like.

If you are having trouble getting rid of the ozone smell, try adding 1-2 drops of lemon essential oil to your purifier. This will help mask the smell if it is still bothering you.

Air Purifiers will remove germs, dust, bacteria, allergens, mold, viruses, and odors that are in the air which will normally cause the smell and will make the air in your home cleaner.

Does an air purifier really get rid of all of the bad odor?

This is a question that many people ask. The answer is yes, it does get rid of most bad odors, but can not remove them completely for everybody. This has to do with the strength of the odor that you are smelling. If somebody has just smoked or introduced something with a strong odor in your house, it will normally be hard for an air purifier to remove all of the scent in your house.

The good news is they will still remove some of it and make it better than without one which is why they are worth buying if you have one of these problems in your home or office.

You can get rid of bad smells

Bad smells are usually caused by bad air quality.

The best way to get rid of bad smells is to find out what they are and then try to remove the source of the bad smell. Oftentimes its something that you are not even aware of. Make sure your house or office isn't sewer gas or methane gas leak, because both of these gases are very dangerous to breathe in over an extended period of time.

If you have any type of fish aquarium inside your house, I would recommend putting something under the tank such as a milk crate for long term use so it doesn't sit on carpet or wood floor because this can release fishy smell into the air and cause you to have a fishy smelling home if not careful.

You can get rid of musty smells

Musty smells can be caused by mold and mildew inside your house. Sometimes the smell of mildew is not always obvious, but it's there if you know what you are smelling for. Most times it will smell like a damp musty smell or moldy smell. This can be bothersome to people who suffer from allergies and asthma because the scent of the mold and mildew is what triggers their allergies and asthma symptoms to flare up.

If you have a musty smell inside, I would recommend getting an air purifier to help get rid of the bad smells because it will work on all types of odors including mold and mildew.

You can get rid of the smells of cooking

An Air Purifier when cooking can leave a lot of odors and flavors and smells and sometimes even burning food. The main purpose of having an air purifier is to remove certain odors and to pipe out any toxic gases which cause the unpleasant smells after cooking.

However, the question still remains as to how to get rid of those lingering odors that you cannot seem to get rid of as soon as you open up your kitchen or as soon as your cook; the answer is simply by using a good air purifier. There are some air purifiers available in the market that help remove those permanent floating smells like fish, chicken and also other kinds of cooking odor.

You can get rid of the smells in your bathroom

Bathroom smells are commonly caused by mold and mildew build up.

An air purifier can help to remove these bad smells by simply circulating the air. Make sure you have a washable pre-filter in your bathroom that you replace on a regular basis so the mold and mildew dust particles are not re-circulated over and over again.

You can get rid of smells from cigarettes

If you smoke, it will leave behind a smell all over your house. If you don't smoke, it's even worse for you because now you have to smell what people are smoking all around you. The most common place I see smokers is near their front doors, which leaves an unpleasant odor in the home. Air purifiers will remove these types of odors from your house or office quickly.

You can get rid of the smells of pets

An air purifier will remove pet odors that are left on carpets, beds, and couches by simply cleaning the air in your house. The good news is that an air purifier works well on both the good and bad scents.

You can get rid of smells in your car

An air purifier will cleanse the air in your car by removing any bad odors that are left inside it. The main purpose of having an air purifier in your car is to remove any bad odors that are left behind. This may be anything from cigarette smoke to old cat litter smells. If you are constantly getting these foul smelling items inside your car, this would indicate that something is not right with the ventilation system and needs to be fixed immediately.

Purifiers can help you to create the perfect environment for your family

An air purifier will make your house or business environment much better because it has the ability to remove bad odors, including the ones that are caused by smoking. Many people are now asking what will happen if they buy an air purifier for their home or office to help clean up their environment. I've found three main benefits that come with using an air purifier which includes:

  1. Reducing airborne allergens
  2. Removing unwanted smells from your environment
  3. Reducing the amount of dust in your environment

Air purifiers have been around for a long time and will continue to be one of the best ways to keep your environment clean and smelling good. A clean home or office is a happy home or office.


If your main purpose is to have a clean environment, an air purifier would be the perfect solution because it will help you get rid of bad odors from any area in your house or office. This includes pets, mold and mildew build up and even cigarette smoke.

An air purifier is a wise investment, so if you have any of these type of problems in your home or office, then you know that it's time to start thinking about getting one. Air purifiers help keep unwanted smells out of our homes and offices which is a wise decision since more and more companies are buying them for more reasons than just the bad smells they remove.
