The U.S. water purifier market size was USD 5.85 billion in 2021 and is projected to grow from USD 6.12 billion in 2022 to USD 9.10 billion by 2029 at a CAGR of 5.8% during the 2022-2029 period. The global impact of COVID-19 was unprecedented & staggering, with these products experiencing lower-than-anticipated demand shock across all regions compared to pre-pandemic levels. On the basis of our analysis, in 2020, the market exhibited a huge decline of 4.5% as compared to 2019.

Water purification systems have gained traction in the country on the back of higher spending capacity and awareness programs carried by agencies such as WHO and the U.S. EPA. The U.S. has primarily sourced water from the great lakes or rivers. But increasing pollution of these resources after the industrial revolution has obligated the usage of treatment systems to safeguard the health of the residents. Filter media eliminate contaminants in the raw water and make it a better quality.

The people in the U.S. are becoming more health-conscious and have taken up regular drinking habits to support the proper working of essential systems. The rising adoption of health apps helping regulate proper drinking habits in the leading app stores is a testimony to this trend. As pure water offers multiple benefits, consumers have turned to water purifier manufacturers to set up purification systems in residents and commercial spaces to ensure a regular clean supply.


Consumer Awareness of Clean Drinking Water to Positively Boost Market during COVID-19

While the entire U.S. was not under stringent lockdown regulations during the pandemic, many states had restricted the transportation of men and materials alike. As purification is a labor-intensive industry, the pandemic resulted in severe supply chain interruption. As many companies import filters from Asian countries, a shortage of material, doubled with a shortage in manpower due to health reasons, was observed across the nation. Many companies couldn’t fulfill the existing orders in time due to logistic failures. This resulted in them facing a capital crunch during the period, affecting their growth potential. However, gradual lifting of lockdowns and the announcement of the industry being ‘essential’ resulted in companies resuming their operations. Many companies took the strategy of advertising the benefits of pure water in the pandemic, thus improving consumer awareness regarding the benefits of their offerings. This trend has provided a push to the market, which was significantly affected during the past year.

Advent of Smart Purifiers is a Key Trend in Market

Smart purification devices are based on technologies such as artificial intelligence (AI) and IoT. They are easy to run and are equipped with multi purification stages, which can be controlled via touch and voice responses according to the consumer's requirement. On the flipside, smart sensors have promulgated across water purification devices to study the quality and display quantities such as TDS, temperature, and O2 content on the screens for the customer to identify the quality. These sensors also send notifications to the consumer and purifier contractors for timely maintenance of filters. Therefore, the advent of these smart technologies is projected to fuel market growth.


Numerous Benefits of Water Purification Devices to Drive Growth of the Market

The primary function of purification products is to remove harmful bacteria, viruses, and other contaminants and make the water safe for drinking and other domestic uses. As per a report by WHO, half of the world’s population is projected to live in aquatic-stressed areas by 2025. Hence it has become essential for purification products to make the maximum possible utilization of water resources. Contamination is a major source of waterborne diseases including dysentery, diarrhea, cholera, and typhoid. WHO estimates that drinking contaminated water causes diarrhea, resulting in around 500,000 deaths every year. By removing cryptosporidium & giardia, purifiers reduce the risk of gastrointestinal diseases by 33 percent. Also, it helps in removing chlorine & chlorine byproducts and lowers the risk of rectal & bladder cancer.

Purification units control the quality of water taste & flavor. Therefore, using clean & pure water for washing & cooking retains the taste of food. Whole house filter systems remove certain minerals, affecting the quality of the overall plumbing system. Filtration to the point of entry improves the life of piping systems and saves the maintenance cost for the same. As water purifiers play many vital roles, their demand is projected to expand in the U.S. in the upcoming years.


Higher Maintenance Cost to Challenge for Market Growth

In order to keep the water quality intact, the filters used in purification should be replaced timely. The replacement benchmarks for particular filters depend on the technology type equipped in the system. In general, point-of-entry filters need to be changed after five to six years, whereas point-of-use filter should be replaced after six to twelve months. This, in turn, increases the maintenance cost of overall purification. Therefore, the higher filter cost represents a crucial challenge to market growth.


By Product Type Analysis

Point-of-Use Filters Held Lions Share in 2021

Based on product type, the market is segmented into point-of-use filters and point-of-entry filters. The point-of-use filters segment is divided into under-the-counter filter, countertop filter, pitcher filter, faucet-mounted filter etc. The point-of-use filters are the largest & fast growing segment in this market. POU filters have compact setups and can be easily installed without acquiring too much space. Low volume capacity makes these filters suitable for lighter applications where water is finally consumed. Reverse osmosis point-of-use water filter are becoming popular due to their higher quality output & space-saving designs.

The point-of-entry systems are fitted at the main line, where water enters the storage and is ideal for treating all household applications. Point-of-entry filters are also known as whole-house filters. The purified water is delivered to the kitchen, bathroom, toilet, refrigerator, and washing machine. Point-of-entry filters are expensive and have a higher treatment capacity than point-of-use filters. Higher capacity & volume make point-of-entry filters more durable.

RO Filters to Lead the Market in the Upcoming Years

On the basis of category, the market is segmented as RO filter, UV filter, Gravity filter, and others. All these categories are traded in offline and online distribution channels in the U.S. Among these, in 2021, RO filters held majority share in the market. RO filters are expensive and specially designed to obtain bottled water quality. These are advance filters, which remove 99% of the contaminants.

Sometimes, these filters restrict vital minerals including calcium, iron, magnesium, which further alter taste. Moreover, the RO filters require timely replacement of filter media, which increases the overall maintenance cost of these filters.

In gravity filters, water is purified with the help of gravitational force. It is filtered from the upper compartment to the bottom without external force. In these filters, mostly activated carbon is used as filter media. Moreover, these filters are comparatively less expensive, easily mounted at any place, and don’t need any electricity & running water to operate. With the proper and timely replacement of filters, these filters last for a longer time.

By Application Analysis

Residential Application to Indicate the Fastest Growth in the Market

The market is bifurcated as residential and commercial based on application. Residential was the leading segment in 2021, and is estimated to remain dominant in the near future. Compared with commercial buildings, water is extensively consumed in household buildings for cooking, bathing, washing, and other tasks. As per the United States EPA (Environmental Protection Agency), an average family in America, daily consumes around 300 gallons water. Approximately 17% goes for cloth washing, 19% via faucets, and 20% for showers. Moreover, rapid urbanization in the country is expected to develop more need to purify water for household application during the forecast period.
