Dust-/Carbon- & Hepa-Filter in sheets?

[moonseeker]

Anybody happen to know where I can buy small "sheets" of above filters. I need to filter outside air being channeled into an enclosed space. Thank you. MS>

Would these electrostatic filter sheets work?

They're available at Tesco and Home Pro, and probably most DIY stores.

Thank you kindly. No, unfortuntaely they would not do the job. I use them for air-con "double-filters. they work well, keeping the air-con dust-free. Thanks again. MS>
