Rob, thanks for joining, and thanks for the 2 questions. And I'll answer the first one about penetrating the markets, and then we'll touch on Legionella after that. And if I don't answer any of them clearly or completely, just please ask more. So how will we penetrate the market? When we look at new technologies such as PFAS, and I mentioned this initially that it's not always the same customer that we're talking to today. So penetrating the market is a good question and a key one that we think about. At the end of the day, we sell our products to the market directly and through distribution. And that is -- those are the 2 channels that we'll continue to enter the market with. And one of the things that we're figuring out is do we have the right partners to talk about PFAS? Do we have the right internal arrangement in order to answer the questions and calls that might come in from organizations that are not the typical hospital networks. And that's the question we answer and look at every day. And we are having to change our model slightly. We're actively pursuing it. But what we find is that at the end of the day, it's still our salespeople are experts internally that end up explaining how their remediation is done. They're still the ones, whether it's through an introduction to a distributor or whether it's through a direct phone call or on marketing leads or a trade show, they still are the ones that are explaining the solution, giving the quote and helping the customer through that solution as they work to remediate that problem. So we're excited about the new opportunity. We're excited about the new audiences that it brings us to and the new conversations that we're able to have. And as our distributors and partners, some who are firmly entrenched in markets where it's health care and some that are not, both have had opportunities. We've seen the non-health care partners more so than the health care-focused partners, bringing up some of those opportunities. And that's fine. That's quite all right, and that's exactly why we have those partners. We don't currently have all of the reach and breadth and relationships that our partners do have, and they've been instrumental in growth. And we still do what we can to make sure that they're successful and that we support them in their needs and their efforts going forward. And that's been working for us. So microplastics, it's not quite as far down the road as I would think that PFAS is, and that's just my observation. And as I think it's because of 2 things. One, measuring a nanoplastic or microplastic is hard. It's difficult to have equipment that can take and separate the microplastics, identify the species and run the centrifuges. It's just hard to do that on large volumes of water to be able to test and identify, but it's more of a reactive and anecdotal based on what's seen as a result of everything. And two, it's -- there's no regulations driving what should be good enough or not good enough. So like the other markets, it just takes time for that to develop. It takes time for just enough people that are smart enough with technology good enough to measure it and to be able to track it and trend it and see what's harmful and not harmful. We remain very well poised to address that when the time comes and even try to drive that market and prompt some of those conversations. So very excited about that and those 2 opportunities. They are, as I mentioned, in summary of that question, first part, different customers usually than we're talking to today, which is often more exciting than anything else. It's a new segment, new bubbles, new TAMs and [indiscernible] to augment. And we remain focused on making sure that the water quality needs of our customers are met, however difficult that might be. Now, regarding your question on Legionella, there has been a lot of publicity. Legionella tends to get the most publicity out of all of the different situations, whether it's norovirus, rotavirus and some of the more difficult. But the truth remains that Legionella still is not the most-costly thing that health care networks are going to deal with. It's those other more difficult to remove pathogens that I just mentioned. I do see more questions being asked about it often, like several in New York City, it's related to air systems such as cooling towers where people are inhaling some of those situations -- some of the viruses and bacteria. So it's not always a water situation that we will address, but happy to have that conversation and give that education. And we do see that those -- that fuel the questions coming in more and more. And it's making us more aware of where the situations are occurring and also proactively able to have the discussion and get people addressing it and looking at it within their facilities. So it's definitely had an effect, I think, on awareness. And as previously mentioned, awareness and education brings customers towards Nephros in the long run every time. We prefer educated customers that do ask those questions, and we're able to talk to them about the creating water safety management programs and the like. So it's very exciting for us. And we hope that the momentum continues along those lines, and we don't hope that people get sick and injured from Legionella, but we do have solutions that will treat that when that does happen.
