What Is An Air Purifier?

Nowadays, many indoor air purifiers are available for apartments, offices, and other indoor spaces to make them feel fresh and airy. An air purifier is a device that filters the indoor air of a closed or enclosed place. It captures polluted air, removes harmful pollutants, and releases clean and unpolluted air. It enhances the natural ventilation system.

Air purifiers help remove the following from the air to leave it cleaner and healthier:

Small Apartment Air Purifiers

  • Allergens
  • Allergens create negative immune responses as allergies or asthma. Common airborne allergens include pollen, dust mites, and pet dander.

  • Mold
  • Mold particles are a health risk and are especially dangerous for people with breathing issues and lung conditions such as asthma.

  • Smoke
  • Filter-equipped air purifiers remove smoke in the air, whether it is from smoking or cooking.

  • Indoor Toxins
  • Indoor toxins are toxic air particles produced from household chemical products such as cleaning and personal care products. When these particles live in the air, they can become harmful to your body.

    How Do Air Purifiers Work?

    Air purifiers sanitize the air and remove harmful substances that are pollutants, toxins, and allergens. Many people confuse them with humidifiers and diffusers, but they’re not the same. Diffusers and humidifiers at Essential oil particles to the air to make it smell better. On the flip side, air purifiers extract dirt particles and pollutants to filter out the air, leaving clean and fresh air to breathe.

    There are different methods to purify the air using an air purifier; some neutralize the air particles, filter and trap particles, and others use negative ion emissions.

    Do Air Purifiers Work?

    Yes! Air purifiers are effective, but they work up to a certain degree and cannot remove or neutralize all the aggravating particles present in the air. This is mainly because many air particles sit on different surfaces around your home, such as furniture, carpeting, appliances, bedding, walls, etc.

    Types Of Air Filters For Small Purifiers

    Nowadays, more and more people are investing in small apartment air purifiers to naturally remove impurities from the air inside their homes and improve their health. But if you are new to the world of home air purifiers, it can be pretty overwhelming to understand different types of air filters and how they work.

    Besides, you need to know so many other things before purchasing the right air purifier for your home. What is HEPA filtration? How does it differentiate from carbon filters? Do you need a medical-grade air filtration system or something to remove the cigarette smoke from settling in? Well, these questions can be confusing for many.

    Let’s walk you through different types of air filters for small air purifiers in an apartment and how they work!

    HEPA Filter

    The HEPA filter is the most common type of air purification filter out there. HEPA is an acronym for High-Efficiency Particulate Arrestance or High-Efficiency Particulate Absorbing filter. These filters remove particles from the air, such as dust, mold, and pollen. So, they help improve air quality by filtering out allergens from the air. Thus, they are very effective for those who have asthma and airborne allergies. A HEPA filter comprises multiple layers of filter material and filters out at least 99.97% of harmful particles from the air that are more than 3 microns in diameter.

    Activated Carbon Filter

    Carbon has multiple uses; from being pressed into diamonds to pencils, it is also used to detox and filter. It is a highly effective filtration material because of its porous nature. Since granular carbon has a large surface with many pores, it can easily absorb contaminants from the air. Thus, it is ideal for filtering indoor air for smoke, gasses, and other toxins that HEPA filters can’t absorb. You can also use it with other reactive chemicals to make it more effective. 

    TiO2 Filtration

    TiO2 is the chemical formula for titanium dioxide. It is the primary chemical compound used as a pigment in white paints. When it comes to air purification, TiO2 can also be used as an air filter. They are used for medical-grade air filtration systems in hospitals. They are also used in home air purifiers to catch pollutants, smoke, germs, and unpleasant odors.


    These types of filters are usually used in conjunction with other types of filtration systems. An ionizer is a device that electrically charges harmful air molecules to form ions, causing air particles to attach to a grounded electrode. It also kills bacteria and viruses present in the air. Ionizers are believed to emit large amounts of Ozone, but that’s just a modern myth. You can find many air purifiers with ionizer filters that are Zero Ozone certified.  

    How Often Should I Change The Filter In An Air Purifier?

    Air purifiers allow you and your family to breathe and enjoy clean and fresh air free from irritants. The purifier catches and traps the irritants present in the air as the air passes through the filters. Dust, mold, pet dander, harmful particles, and other allergens get trapped and accumulate over time. Sooner or later, the filter is saturated. The same is true for activated carbon filters that remove unpleasant odors, smoke, and harmful gases from the air.

    A filter saturated with accumulated pollutants annually becomes ineffective as it runs out of space for new particles. Moreover, air can pass through saturated filters. Thus, you are required to change the filters regularly to make sure the air purifier runs optimally.

    The Answer:

    Now, here comes the main concern: how often should you change the air filter? There is no hard and fast rule that suits all. Some air purifier manufacturers have introduced washable and permanent filters to minimize maintenance and long-term costs. All you have to do is clean out the filter yourself regularly to maintain effectiveness. You can either wash or vacuum them.

    On the other hand, many other air purifiers for a small apartment require new air filters that you have to buy. These are known as disposable filters. But, disposable or reusable, all air purifier filters come with a lifespan. Either you have to replace or clean them after a specific time period.

    Generally, most manufacturers recommend changing the filter every 6-12 months on average. Some also recommend changing filters every 3-6 months. Moreover, people with asthma, allergies, and breathing problems are advised to change the filter every 1-2 months.

    But, you can also simply check whether your filter needs replacement or not. All you have to do is open the air purifier and look at the filter. If you don’t know how to open the filter, you can find instructions to locate the filter in the original manufacturer’s user manual. If your filter is accumulated, change it to ensure your air purifier performs optimally.

    How To Properly Use Air Purifiers In A Small Apartment?

    Air purifiers are quickly becoming an essential commodity, especially for those suffering from allergies or asthma. Air purifiers clean out the breathing air by filtering out any dust, debris, and allergens. They also improve ventilation in small spaces. So, many who live in small apartments are now buying air purifiers.

    But this brings us to an important consideration; how to properly use an air purifier in a small apartment? Well, the answer depends upon different factors:

    The Size Of Your Apartment

    Your first priority is finding an air purifier that can handle the volume of space of your apartment. For this, you have to check the CADR (Clean Air Delivery Rate) number. It is the measure of how effective and efficient your air cleaner is for a given space.

    However, your air purifier’s fan speed and size also influence CADR, so you cannot entirely rely on it. Thus, it would be best if you looked at CADR only as a very rough guideline. For example, if your apartment is medium-sized (500-700 sq. ft.), an air purifier with a low CADR number will not be effective. On the other hand, low CADR (190 ~ 320) air purifiers can work efficiently in small apartments (200-400 sq. ft.).

    How Many Do You Need

    Small apartments do not need multiple air purifiers as most air purifiers out there can cover rooms up to 600 square feet. So, one air purifier is enough for you. Make sure you buy a compact one so you can easily carry and move it around the house.

    Air Purifier Placement

    You can maximize the effectiveness of an air purifier in your small apartment by moving the purifier around to ensure maximum purification. Place the air purifier in your bedroom at night and move it to the living room, kitchen, or office during the day. The idea is to place the air purifier where you spend most of your time. Also, make sure there are no obstructions like furniture/vases/etc., blocking the airflow.

    Apartment Air Purifiers Conclusion

    Anyone who smokes, has pets, or suffers from allergies and irregular breathing should have an air purifier. Even if none of this is your concern, having an air purifier in today’s polluted environment can make all the difference in your health. You will be breathing clean, fresh air every day, keeping your body safe from any toxins, harmful particles, and airborne allergies.
