That's a great question. In our case, we've been offering our customers the filter device. It comes with a filter cartridge in place. It mounts on the faucet. It's a very small device with limited flow capacity. It lasts for, depending on the model, three months or 90 days, and then the cartridges have to be replaced. We've been offering the filter to our customers with the understanding that they will replace the cartridges, so they take the responsibility for the cartridges. We're sharing that responsibility.
We are also seeing those filters as a stopgap measure. We don't really see those as a permanent long-term solution to the lead issue in any given home.
