Dust and debris in a filter restrict air flow, which causes your air purifier to become less effective and use more energy to compensate.But did you know that in many cases you don’t need to change the expensive HEPA filter every time the filter change indicator light turns on? It is often the case that just the pre-filter has become loaded up with larger particles. A clean pre-filter is an excellent way of extending the working life of your HEPA filter. This is especially true for pet owners as pet hair clogs the pre-filter much faster than just dust.Many air purifier manufacturers don’t offer pre-filters separately anymore, this is simply because they make more money by selling the more expensive HEPA filters. With Welham Green Pre-Filter 4-Pack Compatible with Pure Enrichment PureZone Air Purifier you can reduce the cost of running your air purifier.No more time consuming cutting and measuring you’ll have your machine running in a matter of minutes. These pre-filters are specially designed and cut to fit Pure Enrichment PureZone Air Purifier and attach to the velcro strips in the main filter, just like the original pre-filter.
