Fridge freezer sizes explained
Start with the space in your kitchen, not the model name. AO’s guidance says to check height, width, depth and clearance, because large American-style fridge freezers need room not just for the cabinet but for ventilation and door opening too. In the example set, the Hisense PureFlat Infinite RQ758N4SASE is £899, the PureFlat RQ758N4SAFE is £999 and the WiFi-connected PureFlat Infinite RQ758N4SWSE is £1,199, so this is clearly a large-appliance shortlist rather than a compact-kitchen one.
Freestanding vs built-in and other layouts
AO draws a clear line between freestanding and integrated fridge freezers. Freestanding models are the more flexible choice if you may move home or want easier placement, while integrated models sit behind cupboard doors for a neater built-in finish. The Hisense examples in this shortlist are American-style freestanding designs, so they suit shoppers who want big capacity and a statement format rather than a hidden, cabinetry-matched appliance.
Which fridge freezer suits your household?
Think about how you shop, not just how many people live in the home. AO says a bigger fridge share suits households that buy more fresh food than frozen food, so a 70/30-style split can make more sense than an even split if your weekly shop leans heavily on chilled ingredients. The three Hisense examples here are all aimed at large households, which makes them better candidates for bulk buying, batch cooking and bigger fresh-food storage than a compact family model.
What the evidence actually supports
The clearest guidance is practical: AO’s fridge freezer advice centres on size, split type, fit type and features, with measurement checks taking priority before price. The shortlist also gives a useful confidence check, because all three Hisense models show a 4.9 average rating and review counts up to 3,274, while prices sit in a £899 to £1,199 range. That is encouraging, but it is still retailer review data rather than independent lab evidence, and the live AO product pages need checking for final dimensions, capacity, energy rating and delivery details.
How to turn the comparison into a buying decision
Use the shortlist as a decision framework, not a winner list. If fit is tight, measure carefully and confirm the appliance dimensions, door swing and clearance first; if you want a built-in look, choose integrated instead of freestanding; if your shopping is mostly fresh, look for a larger fridge share; and if you want lower maintenance, frost-free is worth prioritising because it reduces freezer ice build-up. The WiFi-connected Hisense PureFlat Infinite RQ758N4SWSE costs more than the £899 and £999 examples, so only pay the extra if app-style convenience is actually useful in your home. Also check the live retailer page for energy rating, running-cost wording, warranty and delivery services before you buy.

Firmness questions
How do I know if a large American-style fridge freezer will fit my kitchen?
Measure the height, width and depth carefully, then leave room for clearance and ventilation. AO’s guidance makes fit checks the first step, because large American-style models need more than just the cabinet footprint.
Should I choose freestanding or integrated for flexibility and kitchen finish?
Choose freestanding if you want easier placement or may move home. Choose integrated if you want the appliance hidden behind cupboard doors for a cleaner fitted look, even if that usually makes installation less flexible.
Is WiFi on a fridge freezer worth paying extra for?
Only if you’ll genuinely use it. In this shortlist the WiFi-connected Hisense PureFlat Infinite RQ758N4SWSE is £1,199, so the premium over the £899 and £999 examples makes sense mainly for shoppers who value connected features.
