Crystal Quest Thunder models explained
Compare 1000, 2000, 3000 and 4000 C/M/CP/MP configurations without treating the stage count as a score.

Read the model suffix
The C and M descriptions refer to different post-membrane cartridge configurations: C/GAC and M/SMART. The P descriptions identify a pressure-pump version. Confirm the supplied layout rather than inferring the entire package from the suffix.
Compare the actual treatment layout
The source chart describes differences in UF positioning and UV components between model families. More advertised stages do not necessarily mean more replaceable cartridges, greater output or independently better performance. Use the full 16-model matrix and the exact model documentation.
Measure the unit and tank together
Leave service access and confirm faucet, drain and power requirements. An older chart and product copy differ on nominal and usable tank figures. Get dimensions and usable capacity for the tank supplied with your model rather than choosing the larger figure from conflicting sources.
Make the replacement list part of the decision
Record each cartridge size, stage and connection, the membrane code and any UV consumables. Some codes occur on more than one listing or do not match the catalog exactly. Ask the merchant to resolve uncertain fittings or substitutions before ordering.
