Subject: individual filters ИМХО предложение выпадает из контекста:The best air purifiers will have individual filters for each of these purposes. Может не individual filters а отдельные индикаторные лампочки для каждого фильтра?We find a filter change indicator light to be extremely helpful, because someone’s ability to actually see particulates in a room to judge whether a hepa filter needs replacing, or relying on smelling odors to judge the life of the gas filter, is not an accurate or scientific way to track the life of the filters. In addition, you would need to remember to check the filters periodically to examine them. The best air purifiers will have individual filters for each of these purposes. A well-constructed air purifier will have a separate pre-filter, gas filter, Hepa filter, and post filter. It will indicate when each of these filters needs to be replaced.
Зарание спасибо :))
