Our take
SKJ-CR021 is a compact manufacturer-documented fan and filter combination with nine speeds, an eight-hour timer and 90-degree oscillation; choose it for the format, not unverified air-cleaning performance.
Consider this compact fan/filter combination when close-range air movement and documented model controls matter; check filter maintenance and exact finish..
Not for shoppers who need a full-height floor tower, independently tested purifier performance, settled room coverage or a confirmed current B0C23XJJMP offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- ULTTY's model page lists nine speeds, remote/touch controls and an eight-hour timer.
- The manufacturer documents a 90-degree oscillation sweep and 120 V / 60 Hz input.
- Its integrated-filter design gives buyers a different format from a fan-only tower.
What to weigh up
- The manufacturer page gives conflicting dimensions, noise figures and room-coverage values.
- Filter certification and claimed capture performance were not independently verified.
- The historical ASIN does not establish a current exact finish or offer.

What the features mean for you
A compact fan and filter, not a full-height tower
The manufacturer identifies SKJ-CR021 as a bladeless tower-style fan and air purifier and lists a height of about 23.5 inches. That compact dimension makes this model a different placement proposition from a tall floor tower: it is more plausible for a nearby table, bedside surface or low location, subject to checking the exact base and clearance. The manufacturer page gives conflicting footprint descriptions, so do not plan around one precise base measurement. Keep CR021 separate from SKJ-CR022D, which the same maker lists as a different product. The historical B0C23XJJMP record does not establish that a current Amazon result is this exact model or finish.
Nine speeds and an eight-hour timer are documented
ULTTY lists nine speed settings, remote and touch controls, three modes and a timer expressed as both eight hours and one to eight hours. For the selector, the maximum supported duration is eight hours. More settings offer a wider control menu than a three-speed fan, but the count alone does not measure airflow or establish that each step produces a distinct sensation. A buyer who values an overnight schedule can treat the listed eight-hour limit as a defined comparison point, while someone needing twelve hours should choose a model with a longer documented maximum. The remote and touch panel are maker-listed controls; app and voice control are not established.
Oscillation and outlet adjustment serve different roles
The manufacturer page lists 90-degree oscillation and also describes an adjustable outlet. The 90-degree figure is the documented sweep value used for matching; it is not an independent measurement of air distribution across a room. Outlet adjustment gives another way to aim the stream, but the page does not establish a measured coverage area. If broad directional adjustment is important, verify the physical control on the exact product and distinguish it from powered oscillation. This model can be compared with ordinary towers on listed sweep, but no source here supports a claim that its purifier fan covers a larger room or circulates air more effectively.
Treat filter language as a manufacturer claim
The page describes a True HEPA/H13 filter and gives a particle-capture claim. Those statements are the manufacturer's product claims; this review did not independently confirm a certification, filtration efficiency or air-cleaning result. The saved sources also do not establish a replacement interval, filter price or long-term maintenance cost. Before choosing a combined fan and purifier, check replacement-filter availability and the instructions for the exact offer. A conventional fan avoids the filter decision, while this model adds a filtration feature that may be useful if the buyer values it and accepts the added upkeep. Do not use the conflicting room-coverage claims as a room-size recommendation.
Confirm the model and ignore conflicting performance figures
The official product page is unusually detailed, but it conflicts with itself on dimensions, noise and room coverage. Those values are not suitable for a precise clearance or quietness comparison. The electrical block lists 120 V / 60 Hz at model-page scope, and the control section lists the speed, timer and sweep facts above. The page does not document app/voice support or water cooling. Its purifier feature does not make this a water-based cooler. Search for SKJ-CR021 and confirm the model and color on the offer; the historical ASIN and a similarly named ULTTY model are not substitutes. This is source-based analysis, not a hands-on purifier or noise test.
What else to compare
Choose a full-height fan-only tower for floor-level placement, or a model with consistent independent coverage tests when room-size performance is the priority.
Before you buy
How many speeds and timer hours does the page list?
ULTTY lists nine speed settings and an eight-hour maximum timer for SKJ-CR021.
Does the air purifier establish a water-cooling system?
No. The manufacturer describes a filter, but the checked page does not establish water cooling.
Is the historical B0C23XJJMP an exact current offer?
No current exact-offer match or finish was verified; confirm SKJ-CR021 on the seller listing.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
SKJ-CR021 offers a compact filter-fan format with documented controls, while its conflicting maker claims and filter upkeep deserve a separate check.
