Air purifiers are powerful air cleaning tools that capture airborne pollutants and filtrate the particles to produce clean air quality within an indoor space. However, in a large home or multiroom apartment setting, one air purifier may not be efficient enough to effectively remove the maximum number of indoor pollutants.
Understanding optimal air purifier utilization for multiroom apartments and homes is the key to achieving maximum air quality protection for the whole household.
How many air purifiers should I have for a house?
Houses or multistory, multiroom living spaces depend on numerous air cleaning devices to achieve comprehensively clean air quality between every room. Houses should primarily utilize built-in HVAC systems to provide whole-house filtration and maximize airflow circulation. For households with multiple individuals or high outdoor pollutant levels, air purifier utilization in conjunction with HVAC systems helps provide the maximum amount of protection against harmful particles sneaking indoors (1).
Ideally, one air purifier should be placed in every moderate to high activity room within a household. However, individual rooms may require different air quality needs and specialized filtration care to properly address pollutant particles (2). As bedrooms are a room where people spend the most amount of time, bedrooms should be prioritized.
How many air purifiers should I have for an apartment?
Air purifiers are designed to care for a limited amount of square footage. Spaces with multiple rooms or large buildings require multiple air cleaning devices to properly filtrate and replace all airborne particles.
For studio apartments or living spaces with very few rooms, 1-2 air purifiers can be sufficient in capturing pollutant particles and filtrating air at an appropriate rate. For multiroom or large apartments, 3-4 air purifiers can provide effective protection against airborne pollutants.
Higher activity levels and outdoor environments could impact air quality, leading to additional air purifier utilization needs. Living spaces larger than apartments, such as houses or multifamily homes, have additional square footage that can house airborne pollutants, requiring numerous air cleaning tools to compensate for the added air particles. Again, bedrooms are a room where people spend the most amount of time, bedrooms should be prioritized.
Do I need different air purifiers for a house vs an apartment?
Generally, standardized HEPA air purifiers work well across apartments and houses, capturing 99.97% of airborne particles up to 0.3 microns in size, such as pollen, pet dander, and dust. However, some rooms in larger houses may produce elevated levels of pollutant emissions due to human activity or environmental factors. These rooms may require advanced air cleaning filters to properly treat various forms of pollutants, such as:
- For HyperHEPA air purifiers: Best suited in spaces with high particulate matter, such as bedrooms, laundry rooms, and offices.
- For activated carbon air purifiers: Best suited in spaces with odors or gaseous emissions, such as garages, nurseries, and bathrooms.
HyperHEPA air purifiers capture 99.5% of particles as small as 0.003 microns in size, filtering ultrafine pollutants such as smoke, chemicals, and traffic emissions. Activated carbon filters are made up of a highly porous surface that is specifically designed to capture harmful gases and odors.
How to calculate the number of air purifiers you need
Houses or multiroom spaces depend on multiple air cleaning devices to properly address extensive square footage – ideally one air purifier per moderate to high activity room. Apartments or low activity spaces could employ fewer air purifiers and still achieve clean air quality. To calculate and double check the number of air purifier needed, Air Changes per Hour (ACH) and Cumulative Clean Mass (CCM) metrics provide quantitative performance data.
ACH measures how many times air particles are replaced in an indoor space within a 60-minute time period. The Centers for Disease Control and Prevention suggests an ACH value of seven or higher as the “best” ventilation efficiency, labeling an ACH value of four as “good” and a six as “better.” Employ multiple air purifiers to increase ACH values in a room (3).
CCM measures how much pollutants and particulate matter can be captured and filtrated before an air cleaning device loses filtration efficiency. Check the outside product packing and look for higher CCM values such as P4 or F4 – the higher the CCM value, the greater the long-term performance of an air cleaning system. Utilizing multiple air purifiers in a space can make up for low CCM values.
IQAir purifiers' CCM demonstrates their long-term performance, with the HealthPro Series room air purifiers independently tested to remove 84 times more particulate matter than the highest test standards, ensuring sustained efficiency for years.
Clean air methods for apartments and houses
While utilizing multiple air purifiers secures maximum air quality protection, daily practices and routine clean air methods help prevent pollutants from even entering indoor spaces. In conjunction with air cleaning tools, daily cleaning in both apartments and homes can help alleviate pollutant presence and limit airborne exposure, such as:
- For studio apartments and RVs: Employ fans to maximize airflow, open windows regularly for ventilation, and run air cleaning devices consistently throughout the day.
- For multiroom living spaces and houses: Clean surfaces routinely to minimize pollutants spreading, install air quality monitors to keep watch on separate areas of a home and utilize multiple air cleaning devices for maximum protection.
Employing efficient air cleaning technology alongside daily practices and air quality monitoring leads to the pathway to maximum pollutant protection and long-term health stability.
Conclusion
Air purifiers are efficient air cleaning tools that remove airborne pollutants, particulate matter, and chemicals from indoor air, but only when the sufficient number of air cleaning devices are utilized. Insufficient quantities of air purifiers or improper filter types can impact indoor air quality greatly, especially in environments with unhealthy outdoor air conditions. Always prioritize the rooms in which most time is spent.
Employ daily cleaning practices and multiple air purifiers in multiroom living spaces, ideally one per room, to ensure clean air quality is achieved behind every closed door.
Frequently Asked Questions (FAQs)
What is the minimum amount of air purifiers I need?
Ideally, every room within a household should host at least one air purifier to effectively filtrate pollutants and produce clean air quality. Spaces with an insufficient number of air cleaning devices could lead to compromised air quality and the spread of airborne pollutants.
How long do air purifier filters last?
Air purifier filters can last anywhere between 1-4 years, depending on filter model, size, environment, and daily utilization.
How many air purifiers do I need for a car?
Personal vehicles and cars are smaller, compact spaces compared to houses and apartments, requiring at least one air purifier to provide clean air quality. Additional air purifiers may be required if the vehicle is large or occupied for prolonged periods of time.
How many air purifiers do I need for an RV?
Recreational vehicles are smaller, compact spaces compared to houses and apartments, requiring at least 1-2 air purifiers to provide clean air quality. The number of air purifiers employed depends on the size of the RV and how long the vehicle is occupied for.
