Record the complete purifier model
Copy the exact model from the air purifier label, including any suffix. Similar names can refer to different sizes or configurations. The brand identifies the appliance being matched; CTT replacement filters are non-OEM aftermarket products.
Find the existing filter identifier
Record the filter number or replacement reference from the filter or appliance documentation. Compare it with the intended purifier models on the relevant replacement filter page. Do not infer compatibility from a similar-looking photograph alone.
Check the physical fit
Provide photographs and measured dimensions. Include locating tabs, frame shape, seals and any separate carbon or pre-filter components. Confirm the supplied replacement against a sample before agreeing the order.
Keep fit and performance separate
A matching shape does not establish filtration efficiency or media grade. State your particle-filter and carbon requirements and request evidence for the actual replacement configuration. Original appliance performance statements do not certify an aftermarket filter.
Match the filter family
The F2MAX type replacement is listed for Blue Pure 211i Max. Filter A / 115115 and Filter H / 116130 have different model lists and configurations. Open the relevant page and check your exact purifier reference before discussing a sample.
Include the rest of the enquiry
Add quantity, pack contents, packaging and destination requirements. If your model is not listed, contact us with its reference and photographs.
