What are the TOOVEM brands?
According to its corporate website, TOOVEM brings together equipment brands and organizes production and sales outside China. It lists AlorAir, Argendon, BaseAire and Abestorm as its brands. It offers factories support with product development, brand building, overseas stores, warehousing and repairs. The company describes a business model combining its own manufacturing with external suppliers. About us and brand portfolio; Partner Center
The connections also appear in the brands' day-to-day operations. AlorAir hosts a remote-control manual bearing the TOOVEM logo. The Argendon-C app in Apple's App Store is published by AlorAir Solutions Inc.; the same account also has AlorAir, AbeStorm and BaseAire apps.
The brands extend beyond dehumidifiers. PuriSystems sells air cleaners and dust-collection equipment. Its US trademark record lists PROSCO as the owner, as do the AlorAir registration and Argendon registration.
Who owns the trademarks?
The United States Patent and Trademark Office, or USPTO, lists PROSCO EMPIRE LIMITED as the owner of the registrations for ALORAIR, A ARGENDON, ABESTORM, BASEAIRE, TOOVEM, PURISYSTEMS, TRIGHTFILTERS. The company was incorporated in Hong Kong, as confirmed by the Companies Registry list, page 179. These records concern rights to US trademarks; ownership of the companies themselves requires separate corporate records.

Owner of the US trademark registrations listed below
On its website, PuriSystems describes itself as a brand of Aramcal Group Inc., while its US trademark registration lists PROSCO as the owner. The website describes the brand's affiliation; the registry identifies the owner of that particular registration.
How the rights moved to PROSCO
Rights to AlorAir, Argendon, Abestorm and BaseAire moved from Chinese companies bearing the Refine name to AlorAir Solutions Limited, then to PROSCO. The sequence is documented in the 2023 AlorAir assignment, 2024 Argendon assignment and assignment of AlorAir and Abestorm to PROSCO. The remaining agreements are linked in the relevant table rows.
| Date | Event |
|---|---|
| November 2023 | Ningbo Free Trade Zone Refine Air Treatment Equipment assigned AlorAir, Abestorm and BaseAire to AlorAir Solutions Limited. AlorAir, 2023; Abestorm, 2023; BaseAire, 2023 |
| March 2024 | Ningbo Refine Industry Technology assigned the Argendon mark to the same company. Argendon, 2024 |
| October 2, 2024 | PROSCO EMPIRE LIMITED was incorporated in Hong Kong. Hong Kong Companies Registry weekly list |
| January 20, 2025 | AlorAir Solutions Limited signed assignments transferring AlorAir, Argendon, Abestorm, BaseAire and TOOVEM to PROSCO. AlorAir and Abestorm; Argendon; TOOVEM and BaseAire |
The AlorAir trademark assignment names AlorAir Solutions Limited. A company with a different full name, AlorAir Solutions Inc., publishes the Argendon-C app and appears in AlorAir's warranty terms and equipment certification records.
When AlorAir and TOOVEM began
AlorAir dates the launch of its brand to October 2016. The US ALORAIR registration was issued on November 28, 2017. An archived TOOVEM company history dates the start of its project to 2019. Launch dates come from company histories; the trademark registration date is recorded by USPTO.
HD35P and AirWerx 35P: matching component numbers
Parts catalogs allow a closer comparison of internal components. The catalogs for HD35P and AirWerx 35P use the same identifiers for the compressor, pump, control boards and the other components in the table.
| Component | Sentinel HD35P | AirWerx 35P |
|---|---|---|
| Compressor | 150220075 | 150220075 |
| Main control board | 150210012 | 150210012 |
| Display board | 150210050 | 150210050 |
| Fan | 150220074 | 150220074 |
| Pump | 15080003 | 15080003 |
| Evaporator | 151110140 | 151110140 |
| Refrigeration condenser | 151110142 | 151110142 |
| Filter, item 2 | 160300080 | 160300080 |
Numbers are taken from the Model field in the official parts catalogs. They identify components within those documents; a retail replacement kit may have a different SKU. Sentinel HD35P; AirWerx 35P
The two catalogs use matching identifiers for the eight components listed above. This is a documented match between catalog numbers; the tables do not establish identical factory-installed components or interchangeability. Sentinel HD35P; AirWerx 35P.
Certification and development
Connections in certification records
Intertek tests and certifies products. In its ETL directory, a record under AlorAir Solutions Inc. groups models carrying the ALORAIR, ARGENDON, BaseAire and ABESTORM brands. Another record contains Sentinel, AirWerx, Guardian and IW-25 models and names Ningbo Kaiyue Import and Export in the Company field. These are connections in certification records; the fields alone do not identify the factory that made each unit.
Equipment development and the Refine name
US patent 10,436,461 B2, issued in 2019, describes a dehumidifier that uses collected cold condensate to precool incoming air. The applicant was Ningbo Free Trade Zone Refine Mould Technology; the named inventor was Rui Zhou.
The USPTO patent assignment record documents a name change from Ningbo Refine Mould Technology to Ningbo Refine Industry Technology. The latter name also appears in the Argendon trademark assignment. This record connects two names of a specific company; it does not disclose the complete ownership chain of all Refine companies.
How the warranties differ
The connected brands cover repair costs for different periods. For example, under AlorAir's updated terms, parts and labor are covered for the first two years. For Argendon, coverage from the second year is limited to the refrigeration system: the compressor, condenser and evaporator.
| Brand | Parts | Labor | Shipping to service |
|---|---|---|---|
| AlorAir | Parts for covered warranty faults during the first 2 years; only the compressor, condenser and evaporator in years 3-6. | First 2 years. Excluded in years 3-6. | Under the Return for Inspection procedure: the company pays within the first 6 months for a valid warranty claim; the customer pays shipping to service in months 7-12. After year 1 through year 3, shipping is the customer's responsibility. Transportation is excluded in years 3-6. |
| Argendon | Parts for covered warranty faults during year 1; only the compressor, condenser and evaporator in years 2-5. | Covered warranty repairs in year 1; refrigeration-system repairs only in years 2-3. Labor is not covered in years 4-5. | Covered in the first 6 months. After 6 months, shipping the faulty unit to service is excluded; transportation is excluded in years 2-5. |
| Abestorm | 1 year for parts; up to 3 years for the coil; up to 5 years for the compressor. | 1 year. Labor is not separately specified for the longer coil and compressor coverage periods. | After the first year, the customer pays both ways. |
| BaseAire | A 5-year limited warranty is stated. The return procedure specifies compressor repair only after year 3. | In months 7-12, the company pays other valid warranty costs. After year 3, the customer pays labor. The page does not give a separate overall labor-coverage period. | The company pays within the first 6 months; the customer pays shipping to service in months 7-12. In years 2-3 and after year 3, shipping is the customer's responsibility. |
The AlorAir row applies to dehumidifiers other than whole-house ducted models. The updated terms apply to orders placed on or after May 14, 2026, and also cover purchases made April 14-May 13, 2026. The BaseAire row covers its low-profile dehumidifiers. The table concerns accepted warranty claims, subject to each brand's exclusions and service procedures. Product Warranty; BaseAire Quality Assurance Policy.
The AlorAir policy treats shipping separately from parts and labor. Return for Inspection applies when a customer declines the proposed service solution and chooses to send the unit to the company. A separate provision covers shipment of replacement parts for minor warranty repairs, which AlorAir pays for.
The BaseAire policy contains conflicting statements about the warranty on a replacement unit. One provision starts the new unit's warranty when it is delivered; another preserves only the remainder of the original term. That page does not establish an unambiguous warranty period after replacement.
Service addresses also overlap: Argendon lists its returns center at 14752 Yorba Ct, Chino, California, and AlorAir uses the same address for repairs. Claims follow each brand's separate contacts and procedures.
What this means for buyers
The USPTO records for AlorAir, Argendon, BaseAire, Abestorm list a common trademark owner. The same brands appear together in an Intertek certification record. Specifications are published by connected brands; repetition across several websites is not, by itself, independent verification.
Repair coverage offers a documented distinction for buyers. If coverage for parts outside the refrigeration system in the second year matters to you, AlorAir's updated warranty provides it; Argendon limits coverage to the refrigeration system by then. This compares warranty terms without claiming that either unit is more reliable.
Capacity and design choices across the ranges are covered in our AlorAir and Argendon reviews. Other brands appear in the dehumidifiers section.
Sources and research limits
This article draws on USPTO documents, Hong Kong Companies Registry records, company websites, the Intertek directory and parts catalogs. Warranty terms were checked against the four brands' policy pages. Research date: October 27, 2026. Aridalia did not test or disassemble the units.
The USPTO trademark records name the trademark owner, while the Hong Kong Companies Registry weekly list confirms PROSCO's incorporation. These documents do not disclose its ultimate shareholders. This research has not established the full structure of the Chinese companies or the factory behind every model. For our approach to evidence, see Aridalia's methodology.
