Salter Dual Air Pro EK4750BLK Review: Salter or Ninja at Twice the Price?
Two 3.7-litre drawers, sync and match, and a three-year guarantee if you register it, for £74.99 at Salter. The Ninja AF400UK costs more than twice that. Which? has tested this Salter, nearly 500 Currys buyers rate it, and the sources cannot agree on whether the drawers go in the dishwasher.
What the three sources agree on
Three sources, of three different kinds. Which? has lab-tested the EK4750 and publishes its running cost and measurements, though not its score. Currys carries 496 customer reviews averaging 4.7 out of 5. And Trusted Reviews bench-tested a Salter Dual Air with the same 3.7-litre drawers. That is a closely related model, but by Trusted Reviews’ own account not this one, so we use its noise reading with that warning attached.
What they agree on: two independent drawers with sync and match, which is why people buy it; a modest footprint of about 39 cm wide and 28–29 cm high; and low running costs, with Which? putting it at £38.27 a year against £45.55 for the Ninja AF400UK.
Salter or Ninja? The Ninja’s drawers are bigger (4.75 litres each against 3.7), and it has a published bench test of its own. The Salter costs £74.99 at Salter against £165–£189 for the Ninja when we last checked, and its guarantee is three years with registration against Ninja’s two. For one to three people cooking a main and a side, the Salter does the job at well under half the price. For a family of four batch-cooking chips and chicken, the extra litre a drawer is what the Ninja money buys.
Two things to check before buying: register it with Salter within 30 days to get the three years (Currys lists only one), and assume the drawers are hand-wash. Salter says they are dishwasher safe, but Which? and Currys say otherwise.
The three reviews this summary is built from
- Which?Lab test of the EK4750, first reviewed August 2023, last checked August 2024. Score paywalled; running cost and measurements public.
- Currys4.7/5 from 496 customer reviews, checked 5 October 2026, on a page that sells it.
- Trusted ReviewsBench test of the Salter Dual Air, a sibling with the same 3.7-litre drawers. Measured 47.6 dB at 15 cm.
Before the review: which Salter did Trusted Reviews test?
Trusted Reviews’ test is headed “Salter Dual Air” and gives no model code. It describes “a total capacity of 7.4-litres, split between two 3.7-litre drawers”. That is the same split as the EK4750BLK, which is the only reason we connect them. But a Trusted Reviews deals page on the EK4750BLK says plainly: “We haven’t actually reviewed this particular model”, calling the tested one “the similar Salter Dual air fryer”. So read every Trusted Reviews figure on this page as a close sibling’s, not this machine’s. The power figures differ too: Salter rates the EK4750BLK at 2,400 W; Trusted Reviews measured a 1,708 W peak on its unit.

What it costs to run
Ofgem’s price cap for 1 October to 31 December 2026 sets the average direct-debit electricity unit rate at 26.32 pence per kWh. A 20-minute session is a third of an hour. At Salter’s rated 2,400 W that is 2.4 × ⅓ × 26.32p = about 21 pence; at the 1,708 W peak Trusted Reviews measured on its sibling unit it is about 15 pence. The Ninja AF400UK at 2,470 W comes to about 22 pence. Both are ceilings, because the element cycles once it is up to temperature. Trusted Reviews’ own figure for a cooking session on its unit was around 16p (0.55 kWh at 30p per kWh, an older rate).
If you want one number, use Which?’s: £38.27 a year for this Salter against £45.55 for the Ninja. Either way, running cost will not decide between them. The price on the box will. Air fryers carry no UK energy label.
Which?
Who they are: Which? is a not-for-profit consumer charity funded mainly by member subscriptions; it takes no advertising or sponsorship, buys almost every product it tests and runs the same lab tests across each category, so its results carry the most weight here.
Which? has tested this machine, which makes it the strongest source here. The catch is that its star rating, Best Buy status and verdict are behind the paywall. It assesses cooking quality on chips and chicken, energy use and cooking time, ease of use including cleaning, and build quality, but we can only report what is public.
What is public is useful. Which? measured it at 29 cm high, 39 cm wide and 37 cm deep, and 6.6 kg, lighter than the 8.3 kg Currys lists. It confirms 2,400 W, two separate cooking zones and automatic switch-off, and puts the annual running cost at £38.27. It also lists the things the machine lacks: no viewing window, no smart controls, no hinged lid and no dishwasher-safe components, which contradicts Salter’s own product page. Which? notes Currys at £99.99.

Who they are: Currys’ ratings come from customers emailed an invitation after buying, collected and moderated by Feefo; Currys offers no incentives and labels reviews from third-party samples as incentivised, so this is good evidence of how owners get on, though not a performance test.
Nearly 500 reviews at 4.7 is a strong number, but it is a retailer’s own ratings block, so cite the figure rather than lean on it as a verdict. The comments we could see stress capacity and convenience (two things on at once, finished together) and did not detail noise or durability problems.
Currys’ listing is also where most of the spec conflicts come from. It gives 220°C maximum, 8.3 kg, 280 × 390 × 350 mm, a one-year guarantee and “hand wash recommended” for the non-stick baskets. The one-year figure is Currys’ statement of the standard cover; Salter’s page offers three years if you register within 30 days, so do that. Currys sells it online only at £99.99, which is £25 more than Salter’s own shop on the same day.
One reliability pattern worth knowing about, though it is not a Currys finding: owners of the EK4750BLK have posted about one drawer stopping working. On JustAnswer, one side that “just flashes stop and won’t work”, and on YouTube, a repair video tracing it to a thermal fuse. Two reports are not a failure rate, but it is the fault to watch for, and the reason to register the guarantee.

An owner repairing this exact model after one drawer failed. Not a review, but the most useful clip here if one side of yours goes dead. Opening the case will void your guarantee. Confirmed by search listing only.
Watch on YouTube ↗ Independent YouTube video, not made by or for Shopbam.Trusted Reviews
Who they are: Trusted Reviews is a UK tech and home review site whose editors use each product and pair that with industry-standard tests in equipped facilities; it says manufacturers don’t vet its reviews and it never takes money to test, so it is a strong hands-on source.
We include this because it is the only source that put meters on a Salter Dual Air, and the drawer split matches. But Trusted Reviews says it has not reviewed the EK4750BLK itself, so treat these as indicative. On its unit it measured 47.6 dB from 15 cm, falling to 40.7 dB at a metre, a 1,708 W peak draw, and about 0.55 kWh for a cooking session. Do not compare those decibels directly with the Ninja’s 60.7 dB from TechRadar: different testers, different distances, different rooms.
Its verdict was “a worthwhile bargain”. It liked the dual-drawer flexibility, the presets, the sync feature and a double-skinned front that stays reasonably cool. It disliked the 200°C ceiling and found operation fiddly, and reported that neither the baskets nor their trays were dishwasher safe. With Which? and Currys, that makes three sources against Salter’s own claim.

The strengths
- £74.99 at Salter, well under half the Ninja AF400UK’s £165–£189.
- Lab-tested by Which?, with a public running cost of £38.27 a year.
- 4.7/5 from 496 Currys buyers.
- Sync and match, the two dual-zone features people use.
- Three-year guarantee with registration, against Ninja’s two.
- Quiet on a sibling test: 47.6 dB close up, 40.7 dB at a metre.
The weak spots
- 3.7-litre drawers: a litre smaller each than the Ninja’s.
- Dishwasher claim disputed by Which?, Currys and Trusted Reviews.
- Owner reports of one drawer failing, traced in one case to a thermal fuse.
- Fiddly controls and a 200°C ceiling on the sibling model tested.
- No viewing window and no smart controls (Which?).
- Guarantee is one year unless you register within 30 days.
Right for you?
Buy it if you cook for one to three, want a main and a side ready together, and would rather spend £75 than £180. Buy it from Salter at £74.99 rather than Currys at £99.99, register it within 30 days, and hand-wash the drawers.
Pay for the Ninja if you cook for four or more and regularly fill both drawers, since 4.75 litres each is meaningfully more room for chips and a whole tray of chicken, or if you want a published bench test of the exact machine you are buying. Read our Ninja Foodi Dual Zone AF400UK review for that side of the argument.
What remains unconfirmed
- Which?’s score and verdict. Behind the paywall. We have used only its public measurements and running cost.
- Noise on this exact model. The only measurement is Trusted Reviews’, on a sibling model with the same drawers. Trusted Reviews says it has not reviewed the EK4750BLK.
- Real power draw. Salter rates 2,400 W; the only measurement (1,708 W peak) is on the sibling. We have costed both.
- Maximum temperature. Currys says 220°C; Salter does not say; the sibling topped out at 200°C.
- Dishwasher safety. Salter says yes; Which?, Currys and Trusted Reviews say no or hand wash. It was not possible to resolve it, so assume hand-wash.
- Weight and dimensions. Currys and Which? disagree (8.3 kg against 6.6 kg; 35 cm against 37 cm deep). Both printed.
- Non-stick coating wear. We found no quantified owner reports of peeling on this model.
- How common the one-drawer fault is. We found two owner reports, not a failure rate.
- The videos. YouTube could not be opened, so all three were confirmed by appearing with the same title and address in two differently worded searches. The listings did not name the channels, and one does not state its model code.
