Filter Pricing
In general, for large quantities, the smaller the filter size, the lower the cost. Manufactured filter sizes range from 2mm square to 50mm diameter, all prices available on request. However, for one-off quantities, our cheapest option is our standard mounted filter.
Standard Holders
- Size: 25mm Diameter (nominal) x 2.5 - 7mm thick
- Discounts applicable for quantities of 3+
- Prices on request for different bandwidths or tolerances
