If you are fed up with cramming food into a standard fridge freezer, the Hisense PureFlat range of American fridge freezers is well worth a look. Models like the Hisense PureFlat Infinite RQ758N4SWFE Wifi Connected Total No Frost American Fridge Freezer in black stainless steel aim to give you serious storage, sleek styling and modern tech without going into luxury-brand price territory. This guide walks you through what to expect from a PureFlat American fridge freezer, how to choose between similar models, and what living with one is really like day to day.
What makes a Hisense PureFlat American fridge freezer different?
American fridge freezers are all about space and convenience, but the PureFlat line adds a few extra touches. The first is the styling: the flat doors and minimal handles are designed to sit neatly with modern kitchens, especially in on-trend black stainless steel or traditional stainless finishes.
The second is flexibility. The Hisense PureFlat Infinite RQ758N4SWFE Wifi Connected Total No Frost American Fridge Freezer uses a multi-door layout rather than the classic side-by-side design. That gives you wide shelves, generous drawer space and usually a flexible compartment you can tailor to how your household actually eats and shops.
Finally, there is the everyday usability: Total No Frost technology, Wi-Fi connectivity and large, clearly laid-out interiors are all designed to take the faff out of food storage rather than just adding flashy extras.
Understanding layouts: multi-door vs side-by-side
Before you get hung up on finishes and smart features, it is worth deciding which layout will work best in your kitchen.
Multi-door layouts (like the RQ758N4SWFE)
The RQ758N4SWFE is part of a multi-door family of American fridge freezers. Typically you get double doors for the fridge section at the top and two drawers or doors below for freezer or flexible zones. This gives you:
- Wide shelves for trays, big salad bowls and party platters
- Easy access to fresh food at eye level
- Large drawers that are great for bulk shopping, frozen meals or family favourites
If you like to batch cook, buy larger joints of meat, or keep an impressive selection of frozen foods, this kind of layout is a strong choice. To see exactly how it is laid out in practice, you can read our full review of the Hisense PureFlat Infinite RQ758N4SWFE.
Side-by-side PureFlat alternatives
Not every kitchen suits a multi-door layout. If you prefer a more traditional side-by-side American design, the Hisense PureFlat Infinite RS818N4TIC Wifi Connected Non-Plumbed Total No Frost American Fridge Freezer is worth a look. The tall, slim fridge and freezer sections give you vertical shelves rather than deep drawers, which some people find easier to organise.
If that sounds closer to what you need, you can dive into the details in our in-depth guide to the Hisense PureFlat Infinite RS818N4TIC. It is a good comparison point if you are torn between a multi-door and classic American style.
Plumbed vs non-plumbed: how do you want your water and ice?
For many people, chilled water and ice on tap is the whole appeal of a big American fridge freezer. The detail to check is whether your chosen model needs plumbing in or uses a refillable tank instead.
Who should consider a non-plumbed model?
If your kitchen layout makes plumbing awkward, or you are in a rented property, a non-plumbed design keeps life simple. You still get chilled water and often ice, but the appliance relies on an internal tank you refill manually.
Several PureFlat alternatives offer this flexibility. The Hisense PureFlat Infinite RQ758N4SWSE Wifi Connected Non-Plumbed Total No Frost American Fridge Freezer in stainless steel is the closest cousin to the hero model, just without the requirement for a water connection. For a closer look, take a look at our full write-up of the Hisense PureFlat Infinite RQ758N4SWSE.
If you like the idea of a slightly different layout, the Hisense PureFlat RF749N4SWFE Non-Plumbed Total No Frost American Fridge Freezer in black / stainless steel is another strong non-plumbed option. You can see how its storage and styling compare in our detailed overview of the Hisense PureFlat RF749N4SWFE.
When is plumbing in worth the effort?
If the RQ758N4SWFE you are considering is the plumbed-in variant, the main benefit is convenience. You will not have to refill tanks, and you can enjoy chilled water and ice whenever you like. That matters more if you have a big family, live in a warm home, or regularly host guests.
Do factor in the cost and logistics of running a water line, especially if your kitchen is already finished. A quick chat with an installer will confirm what is realistic in your space.
Wi-Fi connectivity: handy extra or must-have?
Most of the Infinite-branded PureFlat models, including the RQ758N4SWFE, feature Wi-Fi connectivity. Rather than being a gimmick, it can quietly solve a few real-world niggles.
- Remote temperature checks: If you are away for the weekend and worried about a power cut, you can see whether everything is still running as it should.
- Mode changes on the go: Heading off on holiday and forgot to switch to a more economical setting? You can typically do it from your phone.
- Door and fault alerts: If someone leaves a door ajar, you get a notification before food has a chance to spoil.
The Hisense PureFlat Infinite RQ760N4SASE Wifi Connected Non-Plumbed Total No Frost American Fridge Freezer is another example of a Wi-Fi enabled model in this family. If you are curious about the smarter features across the range, it is worth reading our full breakdown of the Hisense PureFlat Infinite RQ760N4SASE for comparison.
Total No Frost and everyday food care
Total No Frost is one of those technologies that quietly changes the way you use your fridge freezer. Instead of manually defrosting the freezer once or twice a year, a well-designed system keeps ice from building up in the first place.
In practice this means drawers and shelves slide in and out more easily, packaged food does not get stuck in ice, and your usable capacity stays consistent over time. It also helps with airflow, which in turn keeps temperatures more even from top to bottom.
Models across the PureFlat range, from the hero RQ758N4SWFE through to the RF749N4SWFE and RS818N4TIC, are built around Total No Frost, so this is a feature you can treat as standard when comparing within this family.
Capacity, size and fitting an American fridge freezer in a UK kitchen
One of the biggest questions people have about American fridge freezers is whether they will actually fit. PureFlat models are large appliances, and the key is to think beyond just the advertised dimensions.
Check the full route into your kitchen
Do not just measure the gap where you plan to put it; also measure every doorway, hallway and tight turn between your front door and its final position. These appliances are tall and wide, and a narrow hallway can be more of a problem than you expect.
If you think it will be tight, look into whether the doors on your chosen model can be removed temporarily for delivery. Many big appliances are designed with this in mind.
Leave breathing room and door clearance
Fridge freezers need ventilation space at the sides, back and sometimes above. Squeezing one tightly between two walls might affect performance and efficiency. Check the manufacturer’s guidance for minimum clearances and build that into your plans.
Also think about how far the doors need to open for drawers and shelves to slide out fully. In smaller UK kitchens, a multi-door layout like the RQ758N4SWFE can be easier to live with than huge side-by-side doors, but it is still worth marking door swing on the floor with masking tape to be sure.
Energy rating and running costs
Large American fridge freezers have to work continually to keep a big internal volume at a steady temperature, so energy use matters. Many PureFlat models carry an E rating on the modern energy label scale, which sounds middling but is common for bigger appliances that balance performance and size.
To keep running costs sensible in day-to-day use:
- Keep the appliance reasonably full so cold air stays stable when you open the doors.
- Avoid blocking vents inside with boxes or large trays.
- Let hot food cool before putting it in the fridge or freezer.
- Use holiday or eco modes when you are away for long periods.
The Wi-Fi connectivity on the RQ758N4SWFE and similar Infinite models can help you nudge things in the right direction, letting you tweak settings remotely and get alerts when doors are left open.
Styling choices: black stainless vs stainless steel
The colour and finish of a big appliance has a huge impact on the feel of your kitchen. The hero Hisense PureFlat Infinite RQ758N4SWFE is finished in black stainless steel, which tends to suit modern, handleless or dark-wood kitchens particularly well. It can blend more subtly into the background compared with bright silver steel.
If you would rather keep things classic, the Hisense PureFlat Infinite RQ758N4SWSE and RQ760N4SASE both come in stainless steel. These sit neatly with traditional appliances and suit brighter, lighter spaces. The RF749N4SWFE offers a mix of black and stainless styling if you like a slightly softer take on the dark trend.
Living with a large American fridge freezer day to day
Once you have picked a model, it is the small, everyday touches that make the difference between loving it and just tolerating it. The PureFlat series tends to do well here, and there are a few habits you can adopt to get the most from a big American fridge freezer.
Organising your fresh and frozen food
Use zones: one shelf for dairy and deli, one for leftovers and prepared meals, and drawers for fruit and veg. In the freezer, group items like-for-like so you can quickly see what you have. Deep drawers in multi-door models like the RQ758N4SWFE lend themselves to this kind of organising.
Clear containers can stop smaller items from disappearing at the back, and labelling leftovers with dates will help you keep on top of what needs eating first. The extra space is only an advantage if you can see and reach everything easily.
Cleaning and care
Even with Total No Frost, it is worth wiping seals regularly and cleaning up spills quickly so they do not stain or affect odours. A soft cloth and mild detergent are usually enough for the interior; for the exterior, follow care guidance for your specific finish, especially for black stainless and brushed metal.
Once or twice a year, pull the appliance gently forward (if safe to do so) and vacuum dust from around the back and underneath. Good airflow helps performance and longevity on large fridge freezers.
Choosing between the main PureFlat options
If you have narrowed things down to the Hisense PureFlat family but are not sure which way to jump, it can help to think in terms of a few simple questions:
- Do you want plumbed or non-plumbed water and ice? Go for an Infinite model like the RQ758N4SWFE if plumbing suits your kitchen, or consider the RQ758N4SWSE, RF749N4SWFE or RQ760N4SASE if you prefer a non-plumbed tank.
- Which layout fits your habits? Multi-door designs like the RQ758N4SWFE and RQ760N4SASE are great for wide items and deep freezer storage, while the RS818N4TIC offers a more traditional side-by-side split.
- Which finish suits your kitchen? Choose between the dramatic look of black stainless, more neutral stainless steel or combination finishes depending on your cabinets and worktops.
