In 2022, the global home water filter market was $14 billion.

SVT's product penetration in Europe and the United States of America (USA) is high and growing but low in the rest of the world. In 2022:
- SVTs total sales revenue from home water filters was $\$4.9$ billion
- the average revenue earned per water filter was $\$20$
- 90 % of SVTs home water filter sales were to Europe and the USA.

In 2022, SVT announced the closure of its European and USA water filter manufacturing factories. Water filter profit margins had fallen for three years, partly because of increasing costs of energy, rent and labour. SVT has since built a huge new factory in Asia to manufacture home water filters.

SVT's market research, using quota sampling, found that 80 % of households that purchased an SVT water filter:
- had an above-average income
- owned two or more cars.

In January 2023, SVT:
- launched an advertising campaign in Europe and the USA highlighting the lack of potable water for millions of people in less economically developed countries (LEDCs)
- announced a 5 % worldwide increase in the price of its home water filters.

SVT committed to use the revenue from the 5 % price increase to provide two million free WF15 water purifiers annually to charities in LEDCs. It costs SVT $10 to make a water purifier.

Some disagreement occurred among the board of directors regarding this price increase. Some directors felt it would highlight SVTs vision and commitment to helping people in LEDCs, but others believed sales might fall, impacting profits in SVTs Consumer Products Division.
