The industry is the brand
Filter + Pro. No explanation needed on a business card, an email signature or a trade-show booth. The name does the first sentence for you.
Brand asset · domain + multilingual site + brand pack
A domain that says what you do. FilterPro.cn
FilterPro.cn is two English words — readable across languages, built for a global market. Written in Latin letters, it is pronounced and remembered the same way in Chinese, Japanese, Korean and Spanish without translation or explanation. Six companies across five countries already use it for water treatment, automotive filtration and industrial filtration: the demand is real, exclusivity is not.

Premium industry domain
FilterPro.cn
Why this domain
A good domain is not decoration.
A good domain is not decoration.
It is the shortest path to being remembered.
FilterPro.cn does not make people guess. Industry, professionalism and market — three signals in one name. For a filtration business, that kind of clarity compounds over time.
A Chinese supply-chain home
A .cn domain feels natural to Chinese manufacturers, export teams and procurement managers. It is a web address and a statement of presence at the same time.
Zero spelling ambiguity
Nine characters, two common English words, pure ASCII. Easy to say over the phone, easy to print, easy to turn into an email domain.
Five clean years
Registered 2021-07-18 on a 10-year term to 2031-07-18. No site was ever built or promoted, so there is no legacy content, backlink profile or SEO baggage — a clean start from day one.
Industry outlook
Six segments.
Six segments.
All of them growing.
Filtration is not one market but six: industrial dust control, water-filter cartridges, automotive filters, air purification, precision filtration and filtration equipment exports. Growth rates differ — none of them is shrinking.

Note on scope: research firms define “filters”, “filtration & separation”, “industrial dust removal” and “water purifiers” differently. The figures above are not additive. Sources: Fortune Business Insights (2025), GEP Research (2026), AVC (2026), GMI (2026), UN Comtrade via Reuters.
Where the money is
Sell the machine once.
Sell the machine once.
Sell the cartridge for a decade.
The value in filtration is not in equipment — it is in consumables. Equipment is a one-off sale decided on specs and price. Cartridges are a 3–5 year repeat purchase decided on brand trust.
Why does this make a name more valuable?
Consumables have a physical constraint: there is very little room to print on a filter cartridge. So a consumables brand must be short, pronounceable and usable as a trademark. FilterPro is nine letters that fit on the side of a cartridge.
China’s water purifier retail sales were ¥22.9B in 2025, down 4.5% — the hardware side is contracting. Meanwhile the global cartridge market grows at 7.07% toward $24.7B by 2032. Industrial filter bags are now replaced every 3–4 years; China’s automotive aftermarket needs over a billion filters a year.
Sell the machine once, sell the cartridge for a decade. As the industry shifts from hardware to consumables, companies start naming their consumables separately — exactly the window that a “category + tier” name like FilterPro fits.
Why “Pro”
Filter is a category.
Filter is a category.
Pro is a tier.
“Pro” is not decoration. It is the most successful naming arbitrage of the past decade: split one product line into two, sell one on volume and one on margin.
One line becomes two
The standard model carries volume; the Pro model carries margin. Same tooling, two prices.
Borrowing “professional”
Buyers of Pro are not buying specs. They are buying confirmation that they are a professional user.
Making a price rise reasonable
Apple’s 2026 line-up was summarised by the press as “drop Pro, add Pro Max — the more expensive, the better it sells”.
| Domain | Nature | Distinctiveness | Commercial meaning |
|---|---|---|---|
| Filter.cn | Pure category word | Very weak | “Filtration” itself — any competitor can use it, nobody can own it |
| FilterPro.cn | Category + tier | Medium | “Professional-grade filtration” — can anchor a product line or sub-brand |
| FilterMaster.cn | Category + superlative | Weak-medium | Reads like a slogan; hard to carry a serious industrial brand |
Higher distinctiveness does not mean the mark is registrable today. Several parties already use FilterPro in filtration, and the position in China’s Class 11 needs a professional search. This page explains naming economics only; it is not a registrability opinion.
Who it fits
Who gets the most out of it?
Not every buyer is a fit. These six types of organisations can turn the name into a working brand asset.
Automotive & industrial filters
Oil, air, fuel and hydraulic filter manufacturers. Use FilterPro.cn for a product-line site or an export brand that explains itself.
OEM / ODMDust control & environmental equipment
Bag filters, cartridge collectors, flue-gas treatment and VOCs. A direct name lowers the cost of explaining what you do.
ENGINEERINGWater treatment & purification
RO membranes, ultrafiltration, industrial water and home purification. “Professional filtration” carries over naturally.
WATERClean air & cleanrooms
HEPA, FFU, fresh-air systems and cleanroom engineering. Works as a B2B brand or a specialist product division.
CLEAN AIRExport-focused B2B
For manufacturers selling to overseas buyers: an English two-word .cn keeps the Chinese supply-chain identity without a second name to remember.
EXPORTIndustry media, expos & platforms
Trade publications, exhibition sites, sourcing platforms or association projects. A category name makes a natural long-term entry point.
MEDIA / EXPO“
Six entities use it.
That is not a coincidence.
FilterPro is not an unused name in this industry — which is both a risk and proof of demand. Here is what you should know before you bid.
FilterPro is not an unused name in this industry. Public records show at least six companies in the United States, China, New Zealand and the UAE using FilterPro or a close variant, some of them for decades. A US semiconductor company also used the same name for a filter-design software tool. None of this changes who owns the domain, but it does affect how you use it.
This site displays the domain asset only, and has no affiliation, authorisation or endorsement relationship with any entity of the same name. This site does not operate filter products, equipment or engineering services, and does not sell, represent or promote any filter goods or services. The domain is not used for any commercial operation, nor as the official site, redirect target or mail domain of any same-name entity. The asset offered is the domain FilterPro.cn itself, excluding trademarks, trade names, patents, customer lists or any third-party right. Buyers intending to use the domain for filtration products or services should complete their own trademark search and legal due diligence before use.
Out of respect for third-party goodwill, the list below discloses only the number of entities and their countries/regions; full company names and their domains are masked. A complete list is available under NDA.

The demand for the name is real; exclusivity is not.
These six entities show that FilterPro is a term the market keeps choosing — and that no buyer can assume they own it.
The sound use is as a product-line or regional brand, with your own trademark clearance before launch.
We choose to disclose this rather than avoid it. A clean transaction starts with clear information. Please note the seller is not a trademark lawyer and does not provide legal advice — and that masking a name does not mean the underlying facts are unknown.

How it works
Five steps.
Five steps.
Money and domain move together.
The most common risk in a domain deal is transferring first or paying first. We only use third-party escrow or a platform-backed process, so neither side has to trust the other’s word.

Open escrow
The buyer funds Escrow.com, an Aliyun push or another mutually agreed escrow.

Verify & transfer
The new holder completes real-name verification; CNNIC reviews the change; the domain moves to the buyer’s account.

L1CharactersNine letters, two words, .cn suffixObjectively verifiable¥2,000–5,000
L2CategoryFilter maps to six segments that are all growingPublic data¥6,000–20,000
L3BrandPro tiering + six entities proving demandPublic entities¥30,000–80,000
L4StrategicBrand consistency for a namesake / regional brand for exportersNeeds outreach¥188,000–398,000
Why ¥188,000? Start with what it is not. On .cn comparables this name sits in the ¥10,000–100,000 band — tianyu.cn, a two-character pinyin .cn, sold at a fixed ¥98,000 in September 2026, the top of that band for a sector-relevant .cn. ¥188,000 is outside it. This price is not derived from comparables.
It is derived from replacement cost. For a company whose brand is FilterPro, which operates in China, and whose China site runs on a domain that does not match the brand, there are only three ways to unify the name:
Path 1Register a different .cnNew trademark filings + full rebrandExisting recognition reset18–36 mo
Path 2Buy filterpro.comHeld by its owner, not listedNo alternative—
Path 3Buy filterpro.cnEffective on transferNo rebuild needed¥188,000
Registering a different .cn means new trademark filings and a full rebrand of packaging and collateral, with existing recognition reset to zero over 18–36 months; filterpro.com is held by its owner and not listed. The third is the only route that is paid once and unified the next day — and the lowest total cost of the three.
It does not buy a trademark. It buys one entrance. FilterPro is used by six entities across five countries and regions; nobody can own it exclusively. What can be owned exclusively is one thing: the single entrance to that name in the China market. Six entities sharing the name means the search term is a public asset that gets split every day — .cn is the only part of it that can still be held individually. This price holds only for an entity meeting three verifiable conditions: its brand is FilterPro, it operates in China, and its current domain does not match its brand. Very few public entities meet all three. So ¥188,000 is an asking price, not a settlement price — the price moves only against a real offer.

FAQ
Before you bid,
Before you bid,
you may ask.
Something else? Use the form below. We usually reply within 48 hours.
No. The sale covers the domain only, not any trademark, trade name, patent or third-party right. A domain can be transferred cleanly; the right to trade under a name is a separate question. Complete your own clearance before launch.
Yes, subject to the usual rules. A .cn domain can be used with an ICP filing when hosted in mainland China and when the registrant and content meet the requirements. Offshore hosting generally does not require a filing, but mainland access speed may vary.
Usually 3–10 business days with complete documents and escrow. CNNIC real-name verification takes about 3–5 business days. A cross-registrar transfer may trigger a 60-day transfer-out lock; confirm before starting.
No. There is no website and no verifiable organic traffic. The seller makes no promise about traffic, rankings, backlinks or advertising value. You are buying a clean name and a clean start.
The owner is rebalancing a domain portfolio and would rather see it used by a company that can build on it. The sale is not a sign of a problem; the disclosure above exists to make the deal cleaner.
Yes. Include your use case, budget range and timeline. We are more flexible with buyers who will actually use the domain, and we will decline purely speculative lowballs.
No. This is an independent sale page with no affiliation, authorisation or endorsement from any company using the FilterPro name. All trademarks belong to their respective owners. Out of respect for third-party goodwill, this page discloses only the number of such companies and their countries, not their full names.
Six entities use this name.
There is only one .cn.
FilterPro is used by six companies across five countries and regions, but FilterPro.cn exists once. Registered in 2021 and valid until 2031, with no site and no legacy — the earlier you secure it, the less you leave to chance.
