US Air Filtration / Treatment Market Overview

The United States (US) residential air filtration market's key driver include high pollution levels and increasing awareness of health issues associated with pollution, while its barriers and opportunities include operational and maintenance costs and emission of hazardous by-products. On the other hand, the market's aspect that can both be considered a key driver and an opportunity is the popularity of smart home products. Details and insights regarding each market aspect are discussed below.

High pollution levels

  • According to Technavio, the rapid increase in air pollution caused by urbanization, industrialization and emissions by vehicles that eventually affected indoor air quality is the one of the key drivers on the growth of the Residential Air Purifier in the US.
  • Although Technavio's report describes such to be the case, it was also found that through improved environmental regulations, such as the Clean Air Act. A recent report by the Environmental Protection Agency (EPA) shows that the emissions of the six common pollutants has plummeted by 74% from 1970 to 2018 in the US.
  • The reason why the high levels of pollution is still considered a key driver for the Residential Air Purifier Market is that despite the improvement in US air quality, an estimate of 110 million US residents are still exposed to unhealthy levels of air pollution.

Increasing awareness of health issues associated with pollution

Operational and maintenance costs

Emission of hazardous by-products

  • This aspect is a barrier that specifically refers to "ozone generators" or air purifiers that emits large amounts of ozone. According to the California Air Resources Board, ozone is advertised a "healthy kind of oxygen" that purifies air particles, when it is in fact only partially effective in air purification and can instead cause health problems if exposed to large amounts.
  • Such aspect can also be considered as an opportunity, since air purifier manufacturing companies are now offering "ozone free" air purifiers in the market and are one of the top ranking products when it comes to air purifiers.

Popularity of smart home products

  • The increase in the popularity of smart home products has opened new opportunities for the residential air purifier market, which led to the integration of smart connectivity in the market's products.
  • Such feature provides convenience for the consumers as they can now manage and monitor indoor air quality through mobile applications, even if they were to be in a remote location.
  • As reported by Technavio, "integration of smart-connectivity in residential air purifiers is identified as a key trend that will gain traction during the next five years and drive market growth at a CAGR of about 5%".

RESEARCH STRATEGY

Your research team began by looking for any market or industry reports that listed water filtration sales by distribution channel in the US. Some sites that were reviewed were Market Watch, Allied Market Research, and Business Wire. We were able to find some key players in water filtration as well as some global statistics like CAGR and the global market size value. Since we were unable to find any useful information from this strategy, we moved on.

Next, we decided to look at companies that manufacture water filtration systems looking for their financial statements or investor presentations. The statements could list their water purification sales. Some companies we reviewed were Culligan, Everpure, and 3M. Their financial statements didn’t reveal any insights into their sales volume by distribution channel. We were able to locate some investor presentations that listed statistics like but the data found was not usable. Due to this strategy not producing any usable information we moved on.

As a final resort, we decided we may be able to find water filtration sales by reviewing the sales breakdown for places that would sell those types of units. It was assumed that the typical places to purchase a water filtration system would be small hardware stores like Ace Hardware and big-box home improvement stores like Home Depot and Lowes. We searched for any sales information that these companies have made public like their recent annual reports. Although there was plenty of sales data this was all general like their overall sales and their sales by distribution channel. None of the companies broke down their sales data down far enough to identify their water purification related sales.

RESEARCH STRATEGY:

After extensive research, we could not provide a breakdown of air filtration/treatment products sales by distribution channel in the US due to the apparent unavailability of primary research and public information on the market.

In searching for US Air Filtration/Treatment Sales By Retail Category, we took advantage of a compilation of leading scholarly publications and industry databases to put together air filtration sales by retail category. To address this, we searched through market research websites and industry-related databases and media websites for the breakdown of US air filtration/treatment products sales by distribution channel, trends, companies at the forefront of the trend, and what's driving the trend. However, we found no relevant information. The most information we found was related to the global market which was mostly hidden behind paywalls. Thus, no relevant information was obtained.

The report from Research and Markets titled "Global Residential Air Purifier Market—Growth, Trends, and Forecast (2019–2024)" gave insights into key developments in the air purifier market, such as the market's key players which include Daikin Industries Ltd., Sharp Corporation, Honeywell International Inc., LG Electronics Inc., Camfil AB, Whirlpool Corporation, AllerAir Industries Inc., and Panasonic Corporation. Details on the market share, percentage of growth, and any relevant information needed for this request were not available because they are hidden behind paywalls.

The report from TechSci Research described the US air purifier market by filter type (HEPA & activated carbon, Hepa, activated carbon and ion & ozone, electrostatic precipitator, ion and ozone, Hepa, and others), by end-use, competition forecast, and opportunities. There was no mention of distribution channels, trends in distribution, companies at the forefront of the trend, and what's driving the trend. We have also tried to expand our scope to include reports beyond 24 months since most current reports were paywalled. In doing so, we hoped to find data from older reports, from which we can triangulate these percentages. However, there was no pertinent data available.

Next, we tried to find the global or American size by distribution channel for the residential air filtration/treatment products market. We hoped to use any available percentage share for the US in order to triangulate the retail category by distribution channel. However, there was no mention of the global or American residential air filtration/treatment products market distribution size, nor was there any percentage share data to use. Most information available was for the global air filters and filtration equipment market in general, the market's main competitors, as well as issues and drivers which could not be used for our query because the details are not available to the public. We also tried to expand our scope to include reports beyond 24 months. In doing so, we hoped to find data from older reports, from which we can triangulate these percentages. However, there was no pertinent data available.

Next, we tried to build up or synthesize an estimate for the size of the US air filtration/treatment products market by searching for the top players based on revenue in the space. This approach proved difficult because we could not find any befitting ranking. This is because some companies we found, such as Blueair Inc., Honeywell International, Inc., Whirlpool Corporation, Alen Corporation, Sharp Electronics Corporation, Rabbit Air, Winix America Inc., Coway USA Inc., and AllerAir Industries Inc., have multiple revenue streams from other filtration products. Moreover, they have revenue streams from global or multinational markets and they hardly focus on residential products. We have also tried to expand our scope to include reports beyond 24 months, but no data was available through this search method.

We concluded that the unavailability of this information is likely due to the niche nature of the residential air filtration/treatments products market and the fact that most information was hidden behind paywalls. We barely found any data for the global market and data regarding the US, in particular, is especially limited. Also, there were no premium reports that highlighted the residential air filtration/treatments products sales by distribution channel, even if it's operating with a global scope. Thus, we believe that no free primary research has been conducted on this market.

US Air Filtration Market Segments

There are four segments in the US air filtration market: ionic, HEPA, carbon, and UV light. Of those four segments, the three largest are ionic air conditioners (92.1%), ionic air purifiers (4.6%), and HEPA filters (1.8%).

US AIR FILTRATION MARKET SEGMENTS

  • The four types of air filters commonly used across the industrial, commercial, and medical sectors are ionic, High-Efficiency Particulate Absorbing (HEPA), carbon, and Ultraviolet (UV) light air filters.
  • Ionic air filters filter air particles through the production of negatively charged ions. Ionic air filters are commonly used in commercial applications (e.g., air intakes, air conditioners, and HVAC systems).
  • HEPA filters trap particles through a multi-step process involving interception, impaction, and diffusion. HEPA filters’ high-efficiency results in their use in sectors where sterilization is mission-critical (e.g., laboratories, medical clinics, and hospitals).
  • Carbon air filters use activated carbon (i.e., oxygen treated carbon) to absorb and neutralize chemicals and gases. Sectors that require the removal of chemicals from the air use these filters (e.g., cleanroom recirculation and make-up air systems).
  • UV air filters neutralize carbon-based organic compounds (e.g., mold and bacteria) through the photochemical reaction of titanium oxide exposed to UV light. The effectiveness of these filters makes them another candidate for applications requiring sterilization (e.g., water treatment and purification, medical settings, and laboratories).

LARGEST MARKET SEGMENT S

  • The ionic air filter market can be broken down into the following segments:
  • The estimated total market size for ionic air filters is $56.1 billion.
  • HVAC systems primarily comprise the HEPA filter market. The estimated total market size for HEPA filters in the US is $1 billion. The total of these markets combined is $57.1 billion.
  • Using the market size data above to calculate market share reveals that air conditioners have the largest market share at 92.1%. Air purifiers have the second largest market share at 4.6%.
  • HEPA filters have the third-largest market share at 1.8%. Portable air conditioners have the fourth largest market share at 1.1%.
  • Finally, air humidifiers have the lowest market share at 0.5%.

RESEARCH STRATEGY

We began our investigation with an inquiry into air filtration sales in HVAC and engineering industry publications, as well as professional organizations (e.g., the American Society of Heating, Refrigerating and Air-Conditioning Engineers). However, much of the information acquired from these sources was of a professional and academic nature.

Our next strategy was to attempt a triangulation of market size using data from the EPA and the US Department of Energy. However, no information concerning the filter market size was available from these sources.

Our final step was a search for industry market reports. This inquiry yielded three reports with two different market size metrics. The two reports measure sales by the type of technology used. The third report measured market segments by the manufacturing industry.

The market share estimates for residential and DIY air filtration systems use ionic and HEPA systems due to a lack of sales data for carbon and UV filters. However, our research also indicates that carbon and UV filters are used primarily in industrial and medical applications.

Furthermore, many of the higher quality residential air filtration systems use multiple filter types in a single system, which means that some residential air filters would use carbon filters. But we have no way to differentiate the residential and DIY sales from total sales. We have calculated market share using data extracted from a previous project request into the available categories.

The total size of ionic air filters was acquired through a simple sum: 52.6 + 2.6 + 1 + .610 + .2788 = 57.0888 = $57.1 billion.

Market share is calculated using a simple percentage for each category:

Air conditioners: (52.6 / 57.1) x 100 = 92.1%
Air purifiers: (2.6 / 57.1) x 100 = 4.6%
HEPA filters (1 / 57.1) x 100 = 1.8%
Portable air conditioners (.610 / 57.1) x 100 = 1.1%
Air humidifiers (.2788 / 57.1) x 100 = 0.5%

We began our research by combing through industry and market reports like Market Watch, Allied Market Research, Business Wire, and Mintel reports for information regarding the United States market size for water filtration products, and the market growth rate; unfortunately, the reports found were behind paywalls. However, we were able to unearth some key players in the industry like 3M, General Electric, Pentair, Everpure, Ecowater, Brita, Hanston, Flanne, and Culligan water.

Next, we attempted to triangulate the United States market size for water filtration products by locating 3-5 key players in this segment and their market presence in the United States market. We leverage information from the companies’ websites, annual reports, and financial statement. While we were able to unearth 3-5 key players in this segment and their market presence in the United States market, there was limited information regarding the company’s revenue, financial statement for water filtration segment, and their market share. The reason for the limited information was because some of these companies were privately owned, as such was under no obligation to publish its financial fillings.

Lastly, we attempted to provide the estimated market size for the United States water filtration based on its prominent products in the United States market. We were hoping to locate the water filtration products and then summing up each product to provide the estimation on the overall water filtration market. We utilized News articles and the United States water association reports, like Transparency Market Research, Reuters, and US News for information regarding the market size of water filtration products in the United States. The result of this strategy was futile, as we're only able to locate water filtration products like sink water filtration, shower filters, replacement filters, counter tops, and whole houses. This information was not relevant for this request. Our research team, therefore, concluded that information regarding the United States water filtration market size was not publicly available.
