FilterFresh 对比 E-Citizen 的使用情况和统计数据

When did you last change your filter? Most people don't know. Filter maintenance is a chore most people forget about, to the detriment of their homes, appliances, and more. Let FilterFresh be your filter guardian angel! Simply tell FilterFresh about your filters: HVAC, water, air purifier, humidifier, dehumidifier, engine, or whatever kind of filter or consumable you need to replace or clean on a regular basis. FilterFresh will remind you in advance when to replace or clean each one. Use the Today widget any time to get a quick overview of your filters' condition. "Great!", you say. But remembering to take care of a filter is only half the challenge. It's taking the time to go and buy a replacement that can stand in the way of actually changing a filter. Never fear! When you need a new filter, FilterFresh can connect you with resources to locate and purchase that replacement. What could be easier or more convenient?* Sorry, FilterFresh cannot actually perform the maintenance for you. You'll have to do that yourself! Remember to tell FilterFresh you did the maintenance, and FilterFresh will be there the next time to keep you on track. *Product search and purchase available in many geographies including the United States, United Kingdom, Canada, Mexico, Australia, Spain, Taiwan, Hong Kong, Singapore, and Malaysia.
