What are Air Purifiers?
An air purifier for home is a device created to enhance the quality of indoor air by capturing tiny particles suspended in the air on a filter, thus effectively eliminating them.
While they can be useful in reducing pollutants, it’s important to recognize that air purifier for home are just one element of managing indoor air quality.
They work most effectively when used in conjunction with other approaches like cleaning, ventilation, and removing sources of pollution.
Additionally, it should be noted that their effectiveness is confined to the specific area where they are located and may not address pollutants found elsewhere within the home.
Types of Air Purifier
A common classification for portable air purifier for home includes filtered air purifiers, electrostatic air purifiers, and UV light air purifiers.
Filtered top rated air purifiers effectively capture and trap airborne pollutants by utilizing filters. While, electrostatic options rely on charged particles to gather contaminants, while UV light models utilize ultraviolet radiation to target specific pollutants such as viruses and bacteria.
However, experts have expressed concern regarding the potential emission of ozone and other harmful substances from electrostatic and UV-based air purifiers for dust allergies.
Consequently, filtered air purifier for home are generally regarded as the safest choice for residential purposes. It is worth noting that both the FDA and EPA neither certify nor endorse any specific brands or types of devices used for cleaning indoor environments.
Factors that Differentiate Air Purifiers
Air purifiers vary in several critical factors, which are as follows: –
Filter Type and Quantity: Air purifiers for dust allergies including the best air purifier for asthma utilize different types and quantities of filters. For instance, they may use HEPA filters that are specifically designed to capture minuscule particles effectively.
Coverage Area: Each air purifier for home has a specific square footage range within which it can efficiently clean the air.
Airflow Rate: The airflow rate refers to the volume of air drawn through the filter every minute (measured in cubic feet per minute).
Efficiency Rate: The efficiency rate indicates how well an air purifier for home can collect indoor pollutants. This is often expressed as a percentage.
Clean Air Delivery Rate: The amount of clean air that they can deliver, ideally suitable for the room’s dimensions.
Weight and Portability: How easy it is to move them around and their portability.
Targeted Contaminants: The specific pollutants that air purifier for dust allergies or air purifier for asthma are designed to target and remove.
Pollutant Source Strength: The intensity and nature of pollutants present in the surroundings.
To effectively filter out particles, it is recommended to use HEPA filters with a minimum MERV rating of 13. Furthermore, for wildfire smoke, it is advisable to choose an air purifier for dust allergies with a higher CADR that matches the size of your room.
Some models offer specific CADRs for different types of pollutants such as smoke, dust, and pollen which allows you to select one that meets your needs. Before making a decision, consider the dimensions of your space, the capabilities of the air purifier for home, and the contaminants you wish to target.
How do Air Purifiers Work?
Step 1: Air Intake
The top rated air purifiers are equipped with a fan that works to draw in surrounding air from the room into the purifier itself. By doing so, any particles or pollutants present in this air can be effectively directed towards and removed by the purifying mechanism.
Step 2: Air Filtration
Next, once inside the purifier, the drawn-in air undergoes filtration through one or more filters. These specialized filters in air purifier for home have been designed specifically to efficiently capture various types of particles and pollutants.
Typically composed of materials such as paper, fiberglass, or mesh which possess fine pores for trapping contaminants while allowing clean air to pass through seamlessly during its journey within it.
Step 3: Particle Capture
As the air passes through the filter, it effectively captures various particles such as dust, allergens, pet dander, smoke particles, and other impurities. These pollutants are trapped within the filter material and do not re-enter the room’s air supply. This process ensures that only clean and purified air is discharged back into the environment.
Step 4: Clean Air Discharge
Once thoroughly filtered, the purified air is released into the room without any contaminants or impurities present. This promotes better indoor air quality by reducing potential allergens and irritants in your living space.
Step 5: Regular Maintenance
It is important to uphold the ongoing effectiveness of the best air purifier for asthma. Certain filters can be washed and reused, while others, especially those in more advanced air purification systems, require replacement after a designated timeframe.
It should be noted that filter replacement incurs additional costs that need to be taken into consideration.
Step 6: Ionization (Optional step)
Some top rated air purifier for dust allergies incorporate ionizers as an optional feature, which emit negative ions to aid in the settling of particles from the air.
However, it is important to ensure that these ionizers do not release excessive levels of ozone, as this can irritate lung tissues. If there are concerns about ozone emissions, it is advisable to operate the air purifier for home without activating their ionization functionalities.
What Type of Household Contaminants are Removed by Air Purifiers?
Common Allergens
Indoor environments are often filled with substances known as allergens, which can trigger symptoms of allergies. Some common examples of allergens found indoors include:
- Pollen: This outdoor allergen finds its way into indoor spaces through various openings.
- Pet Dander: Microscopic skin flakes shed by animals such as cats, dogs, and birds.
- Animal Dander from Involuntary Infestations: When pests like rats or mice shed dander in a concentrated manner.
- Cockroaches: Release chitin and other substances that act as allergens.
- Dust Mites: These tiny mites thrive in humid conditions and feed on discarded human skin cells.
Research Insights
HEPA air purifier for dust allergies have the potential to alleviate indoor allergies caused by common allergens such as plant pollen, dust mites, and animal dander.
However, the efficacy of air purifier for dust allergies may vary when it comes to reducing dust mite and animal dander levels. Some studies suggest that these types of allergens tend to settle quickly on larger particles and might not be effectively captured by air purifiers.
Mold
The growth of mold can present significant challenges, especially for individuals with asthma and allergies, particularly children.
Mold is a type of fungi that thrives in damp conditions, indicating an underlying issue with moisture. It reproduces by releasing spores into the air, which may cause mold-related allergies resulting in symptoms such as sneezing, irritation of the nasal passages and throat, a runny nose, and itchy or red eyes.
Research Insights
According to the EPA’s research studies conducted on best air purifier for asthma, indicate that they can remove some airborne mold particles but are not effective at resolving mold issues entirely.
In order to effectively address problems caused by mold growths completely identifying sources of excess moisture must be done.
Indoor Smoke
Indoor smoke can stem from a variety of sources, such as tobacco, e-cigarettes, incense, and wood-burning stoves.
It is important to note that while the best air purifier for asthma are effective in reducing the presence of smoke particles in the air, they may not fully address non-particle components found in smoke.
Research Insights
Although HEPA air purifiers for home can help reduce airborne smoke particles to some extent, they may fall short in addressing other chemical constituents present in smoke which are equally problematic for health.
Gaseous pollutants
Gas pollutants that are commonly found indoors include carbon monoxide, nitrogen dioxide, ozone, and volatile organic compounds.
When trying to effectively remove these gases from the air, it is recommended to select an air purifier for dust allergies with activated carbon filters rather than HEPA filters.
Research Insights:
Various air purifier for dust allergies claims to reduce VOCs as they consist of consumer-grade cleaners, according to a study conducted by the American Chemical Society.
In fact, some even released additional harmful VOCs into the environment. This emphasizes how crucial it is for you to ensure that your selected air purifier has been specifically designed to filter out the particular VOCs you are worried about.
