Pros and cons
AlorairCrawlspace
Pros
- Running cost is easy to plan: media at $32.95 to $65.90 with changes at 3 to 6 months.
- Generous coverage of 93 to 418 m² per unit, with a mobile app for readings and settings.
- Support runs on email, chat and phone, so phone and live chat both sit behind the warranty.
Cons
- Entry at $343.73 ranks 67 of 76 brands, so the purchase carries the cost.
- Filtering is ioniser only, while much of the field offers HEPA media instead.
- Shipping covers US, so buyers in other countries source and import the unit themselves.
Pure Enrichment
Pros
- Entry pricing of $32.99 puts the range below the air purifier field entry median of €136.80.
- Covers purifier, dehumidifier and humidifier types, so one maker handles damp air and dirty air.
- Filter layers list hepa h13, carbon and uv, so a single tower handles particles and odour.
Cons
- Clean air delivery of 203.88 m³/h sits below the purifier field median of 437.43 m³/h, so large rooms need longer run times.
- Replacement filters run $43.98 to $99.98 a year, and the top of that range is well above the field cartridge median of €44.42.
- A 6 month filter change interval means frequent filter handling and extra spend.

Questions about each
AlorairCrawlspace
What does the AlorAirCrawlspace cost up front?+
Entry price starts at $343.73 for the base Sentinel dehumidifier, and the wider Sentinel range sits above that. That buying figure is the higher end of the category, so the outlay deserves attention before the running years are counted. Models further up the range add capacity rather than a different kind of machine.
What are the running costs once it is installed?+
The ongoing cost is the filter, listed at $32.95 to $65.90 for replacement media. Extraction is 35 litres a day under the test conditions in AHAM (80F, 60% RH), a cooler and drier setting than a crawl space in a humid season, so treat the quoted output as a ceiling. Filters come round every 3 to 6 months.
Pure Enrichment
What does a Pure Enrichment purifier cost to buy?+
The range starts at $32.99, which is well under the air purifier field entry median of €136.80. Entry buyers get a purifier, but the ongoing filter bill matters more than the ticket, and filters cost $43.98 to $99.98 a year across the range.
What are the running costs for filters and power?+
Replacement filters run $43.98 to $99.98 a year, with a 6 month change interval, so filters are the main ongoing cost. The purifier draws 46 W, and the low noise level of 36 dB means it can stay on low in a bedroom without becoming intrusive.
